Every integration test picked a port by opening ServerSocket(0), closing it and
reusing the number, which races anything else on the machine between the close
and the rebind. FlashApp.port() reports the port the listener actually bound,
so the guess is gone: 18 freePort() helpers deleted, 40 call sites now pass
port(0) and read the result back.
Two ServerSocket(0) uses remain and are correct. ConnectionRunnerTest accepts
on its socket rather than using it to pick a number. H2LoadMeasurementTest
hands its port to an external nghttpd process, which has no equivalent of
port() to read back; that one is now commented to say so.
HttpServerTlsTest's two-listener case reads both back through ports().
HttpServerTest and HttpServerConcurrencyTest also move from @BeforeEach to
@BeforeAll — every test in them is read-only against the same routes, so 11 and
3 boots respectively become 1. HttpServerConcurrencyTest's lazy-compile test
keeps building its own app, since a freshly compiled router is the thing it
tests. HttpServerTest now runs 11 tests in 0.06s.
The http2 interop suites (curl, nghttp, grpcurl, h2spec), the load measurement
and the soak test are skipped without their external binaries or system
property, so those edits are compile-verified here and exercised in CI.

Four small seams, each useful on its own, that together make a Flash app
testable without hand-rolled scaffolding.
- ServerHandle/ServerLifecycle/FlashApp gain port()/ports(). Listeners already
bind in the FlashApp constructor, so port(0) resolved to a real port that
nothing could read back; every integration test worked around this by
opening a ServerSocket(0), closing it and reusing the number, which races
anything else on the machine.
- FlashContext.override() replaces a binding instead of rejecting it. The
duplicate-is-an-error rule stays everywhere else; this is the single
deliberate exception, for swapping a service out in tests. A replacement is
logged at INFO so misuse in production is visible.
- FlashApplication + FlashApp.apply() name an application independently of the
port it runs on, so the same one can be booted twice. It takes FlashApp
rather than FlashRegistrar because ws() and mount() live there. Being a
functional interface, a lambda and a named class are the same thing.
- FlashContext.onClose() runs cleanup at stop(), children first and then in
reverse registration order. stop() previously closed sockets and the
executor and never touched the service graph, so a pooled DataSource was
only ever released by JVM exit — invisible with one app per process, a leak
per test class once a suite boots and stops many.

FlashRegistrar#any() registers a handler under every HTTP method for
verb-indifferent handlers (e.g. a reverse proxy). OpenApiExtension now warns
when a class-based handler has no @ApiOperation instead of silently omitting
it from the spec. AbstractRouter's default production exception handler now
logs unhandled exceptions server-side instead of only returning a JSON 500.

Http2ResponseWriter.streamBody (a streaming response's InputStream, driven
across startFlowControlled/resume as flow-control windows allow) was never
closed anywhere -- not on clean EOF, not on a write failure, not when the
stream is abandoned (RST_STREAM from the peer, connection teardown). Same
bug Http1ResponseWriter had before cf16be0, just never given the same fix: a
handler stream that releases a held resource (a pooled backend connection,
for a reverse proxy) from close() leaks it under any real amount of stream
resets or aborted connections.
- appendData closes streamBody once `end` is reached (clean completion) and
on any IOException from the read itself, mirroring Http1ResponseWriter's
relayAndClose/writeChunkedAndClose reasoning.
- New Http2ResponseWriter#abort(), called from Http2Stream#cancel() --
symmetric with that method's existing http2Body.cancel() for the inbound
leg, now covering the outbound one too. cancel() is the single hook every
abandoned-stream path (RST_STREAM handling and connection teardown in
Http2Connection, plus Http2StreamDispatcher) already goes through, so this
covers every abort case without adding a new one.
closeStreamBodyQuietly() is idempotent (nulls streamBody after closing), so
the appendData and abort() close paths can't double-close or race.
Four new Http2ResponseWriterTest cases: normal completion in one call,
completion across a resume() (multiple flow-control windows), abort() while
still streaming, and abort() as a no-op on a non-streaming response. 697/697
flash-module tests green.

Claude-Session: https://claude.ai/code/session_011LLwcyHUnbApCrY33gvgoa
WebSocketSession.close(int) hand-wrote a raw, always-unmasked 4-byte CLOSE
frame, bypassing writeFrame's maskOutgoing handling that sendText/send/
sendPong already go through correctly. A client-mode session (maskOutgoing
true — WS-client usage, e.g. Pathway's UpstreamWebSocketConnector relaying a
proxied client's close to a backend) therefore sent an RFC-6455-invalid
unmasked frame.
This was latent until this same HTTP/2 branch's readFrame rewrite added the
receive-side masking check RFC 6455 §5.1 requires: a strict peer now rejects
the malformed frame with WebSocketProtocolException("client frame must be
masked") before ever exposing it as a CLOSE, silently dropping the close
instead of relaying it — reproduced end to end via Pathway's
ProxyWebSocketIntegrationTest.clientCloseIsForwardedToTheBackend.
close(int) now builds its 2-byte payload and calls the same writeFrame path
every other outgoing frame uses, so masking (or not) follows maskOutgoing
automatically. Existing server-mode close_setsClosedAndWritesFrame is
unchanged (byte-for-byte identical output — no mask bit, no key). Added
close_masksWhenActingAsClient (mirrors the existing sendText coverage) and a
round-trip regression, readFrame_acceptsCloseFrameWrittenByAClientSession,
that reproduces the actual bug: a client session's close() output fed
straight into a server session's readFrame().

HttpProxy and Http2Client (719 LOC) shipped a reverse-proxy adapter and outbound HTTP/2
client from flash core with zero callers anywhere in the server itself — only each
other and their own tests. An HTTP/1.1+2 server framework has no business bundling an
outbound client; that capability belongs in its own flash-extensions/flash-ext-*
module if/when it's needed. Removed, along with the now-dead src/bench load driver
that depended on Http2Client (no replacement client written here — flagged as
follow-up work, not silently dropped).
docs/http2/ had accumulated core, cross-protocol documentation alongside genuine
HTTP/2-protocol internals: HTTP1-HARDENING, TRANSPORT, MESSAGE-MODEL,
TRAILERS-AND-STREAMING and BYTES all describe machinery HTTP/1.1 and HTTP/2 share, not
HTTP/2 specifically. Moved to a new docs/core/, leaving docs/http2/ to the protocol
layers, wire internals and operational docs that are actually HTTP/2-specific.
CLEARTEXT-AND-PROXY.md renamed to CLEARTEXT.md and its now-removed upstream-client
section cut, matching the source removal above.
README.md: removed the "HTTP/2 upstream proxy" section (documented the deleted
HttpProxy/Http2Client), the flash-bench module row and build command (not a module
that exists in this repo), and fixed every doc link to the new docs/core/ paths.
Added the new FlashConfiguration.maxConnections field to the configuration reference.
src/bench/ (a load-test harness distinct from the JMH suite, not wired into any Maven
profile or CI) is committed here for the first time.
Targeted stress testing under this branch's HTTP/2 work surfaced four independent
production bugs, each verified with a before/after load test and a regression test:
- Http2Limits.MAX_STREAMS_CREATED_PER_INTERVAL (400/10s) rejected legitimate
high-concurrency HTTP/2 clients as if they were CVE-2023-44487 rapid-reset abuse —
h2load's default pattern alone triggered 40-92% request failure. Raised to 100,000,
matching MAX_STREAMS_PER_CONNECTION's existing lifetime budget; the RST_STREAM-rate
counter remains the precise defence against the actual attack signature.
- Flash had no connection-admission control anywhere: AcceptLoop accepted every TCP
connection unconditionally, so a connection flood (h2load -c 400) ran the JVM out of
heap and crashed with OutOfMemoryError, killing even unrelated daemon threads.
TransportLimits.defaultMaxConnections() auto-scales a cap from Runtime.maxMemory();
ConnectionRunner.accept() enforces it before any per-connection state (TLS handshake
included) is created. Verified surviving 42x the admission limit under both cleartext
and TLS load with bounded RSS.
- Http1ResponseWriter never closed a handler's streaming response body on a write
failure (e.g. the client disconnecting mid-transfer) — only on a clean EOF. A handler
whose stream releases a held resource (a pooled backend connection, for a reverse
proxy) from close() leaks it under any real amount of client disconnects. Now closed
on every exit path, matching InputStream#close()'s own idempotency contract.
- Http2StreamState.transition() called the enum's values() every state transition;
values() clones a fresh array on every call. Cached once, removing ~10.76% of
allocations measured live under load.
695 -> 698 tests (three new regression tests), all passing.
Pools Request/RequestBody/RequestLine/Response per connection (EX-20..EX-24),
following the same reset()/dev-mode-guard idiom Http1HeaderMap already used.
HeaderMap splits into HeaderView (interface) + Http1HeaderMap (impl, DEC-22).
Response gains byte-level structured headers, PreEncodedHeader, and
ResponseSerializer as the single source of truth for a response's header
sequence, consumed by Http1ResponseWriter's single-bulk-write rewrite (EX-27).
ByteTemplate gets O(1) slot lookup plus a buffer-writing overload (EX-28).
Multipart audited: three resource-exhaustion gaps found and fixed — unbounded
buffered part size, part count, and per-part header parsing (EX-38..EX-40) —
and boundary length confirmed already bounded (EX-41).
Re-measuring RequestPipelineBenchmark after the pooling work surfaced one more
per-request allocation underneath it (RequestParser building fresh
RequestByteViews every call) and, while checking the phase's own DoD text, an
unbounded Response.header(...) loop hazard neither had a limit — both fixed
(EX-42, EX-43). The h1 zero-alloc contract now holds: parseAndRoute measures
0.008 B/op (JMH noise floor), down from Phase 4's 120.008 B/op (DEC-20, DEC-23).
MESSAGE-MODEL.md records the pooling model; README gains an "Object lifetime"
section documenting the do-not-retain-past-the-handler contract. 503/503 tests
green.

Implements HTTP/2 frame reading, validation, and writing: FrameType (the
10 RFC 9113 types + per-type validation descriptor), FrameFlags (with
the deliberate END_STREAM/ACK bit collision documented), FrameHeader (a
flyweight, never allocated per frame), Http2FrameReader (length-prefixed
reader over BufferedByteSource, mirroring RequestParser's buffer/
compaction discipline), FrameValidator (table-driven, specific RFC error
code per violation -- not a uniform code per type), Padding (RFC 9113
6.1/6.2), and FrameWriteBuffer (beginFrame/endFrame length back-patching
over Phase 4's ByteWriter).
All 10 frame types round-trip correctly; every RFC-mandated rejection
has its own test asserting the specific error code; the reader is
fuzz-tested against 10,000,000 random inputs (~14s). The zero-alloc
contract is measured, not asserted: reading + validating + consuming a
frame is 0.002 B/op, writing one is ~10^-4 B/op -- both indistinguishable
from zero (DEC-21).
Found and fixed EX-37 while writing Http2FrameReaderTest: BufferedByteSource's
deadline mechanism (EX-07's actual fix) NPE'd against a null socket, which
every isolated unit test in this codebase uses -- it had zero dedicated
test coverage of its own. Fixed to treat a null socket as "no OS-level
timeout to bound" rather than a misuse, and given BufferedByteSourceTest,
which did not exist before.
449/449 tests green, both with and without -Pjmh.

Builds dev.relism.flash.bytes: ByteScan (scanning/comparison/hashing,
scalar + SWAR, property-tested against each other on every boundary and
20,000 random fuzz trials each), ArrayBackedByteView/SegmentedByteView
capability hierarchy, PooledSlice/SlicePool, ByteWriter, Pairs.
Cashes in the allocation and scanning wins the existing code left on the
table: EX-04 (word-at-a-time router matching, verified directly against
fpr-core's own ByteCompare), EX-05 (pooled views replacing per-call
anonymous ByteView allocations in HeaderMap/QueryParams/PathParams),
EX-09 (HeaderMap index built once per reset() instead of rescanning per
lookup), EX-19 (reusable PathParams on the router's per-connection
scratch), EX-25/EX-26 (single-allocation String construction), EX-33
(SWAR header-terminator scan in RequestParser).
Also closes EX-06's router half, missing from this phase's own EX-item
list in the plan (same class of omission DEC-12 recorded for Phase 1):
FastPathRouterImpl/FastPathWsRouterImpl's ThreadLocals (unbounded under
one-virtual-thread-per-connection) are replaced by an opaque,
caller-owned per-connection scratch object (AbstractRouter#newScratch),
not by extending ConnectionScratch as its own Javadoc originally assumed
-- that would have created transport's first dependency on routing in
the reverse direction. Full rationale in DEC-19.
Every optimization is measured, not asserted (DEC-20): SWAR scan 35.4%
faster than scalar, kept; EX-04's word-path 32.1% faster than
byte-at-a-time at the mechanism level, kept for its real future
consumers even though today's router doesn't yet route through it
(MethodPathByteView stays deliberately non-array-backed, per the plan's
own text). Router matching itself is ~0 B/op including parametric
routes. The full h1 pipeline is not literally 0 B/op yet -- 120 B/op is
Request/RequestBody/RequestLine construction, honestly attributed to
Phase 6's explicit scope rather than hidden.
395/395 tests green, both with and without -Pjmh.

Implements the connection-level serialized frame writer per the plan's
go/no-go gate: tryLock() fast path with an intrusive Vyukov-style MPSC
fallback under contention, ReentrantLock throughout (never synchronized),
and a scan-based write-timeout reaper.
All four gate criteria met and measured: N=1 0 B/op and 42.6 ns overhead
(<=50 ns budget); N=64 65.5% throughput retention (>=60%) and 11.8-14.2 us
p999 (<1 ms); no carrier pinning; stress test 10,000/10,000 green across
1000 iterations x 5 concurrency levels x 2 scheduler configs. Compared
against plain-lock and dedicated-thread designs with real benchmark
numbers, not assertion. Full methodology and results in WRITER.md, DEC-09.
Also fixes a real regression found while resuming this work: the JMH
benchmark broke plain `mvn test` (no -Pjmh) because it lived in
src/test/java, which Surefire's test discovery loads regardless of
whether a class is ultimately selected as a test. Moved to a dedicated
src/jmh/java source root registered only under the jmh profile
(build-helper-maven-plugin), per DEC-17.

Breaks HttpServer (563 lines, eleven responsibilities) into named,
single-purpose components and introduces the ConnectionProtocol seam
HTTP/2 plugs into starting Phase 8, per
flash/docs/http2/IMPLEMENTATION-PLAN.md Phase 2.
New packages:
- dev.relism.flash.transport: TransportFactory (composition root, EX-34),
ListenerBinder, BoundListener, TransportTuning, AcceptLoop,
ConnectionRunner (per-connection setup/teardown), ConnectionProtocol
(the h1/h2 seam), ConnectionContext, ConnectionScratch + ScratchPool
(EX-06), ServerLifecycle (implements ServerHandle; start/stop/graceful
shutdown, EX-32).
- dev.relism.flash.http1: Http1Connection (the keep-alive request loop,
implements ConnectionProtocol), Http1ResponseWriter, Http1KeepAlive
(the shared Connection-header token-list scanner, EX-13).
- dev.relism.flash.websocket additions: WebSocketUpgrade (detection +
handshake), WebSocketLoop (session loop), WebSocketProtocolException.
Existing-code defects fixed (EX-nn):
- EX-01: WebSocketSession's two blocking-write sites use ReentrantLock
instead of synchronized (out) -- a virtual thread blocking inside
synchronized pins its carrier platform thread on Java 21.
- EX-06: HttpServer's three ThreadLocals (SHA1, LONG_BUF,
STREAM_RELAY_BUFFER) replaced by ConnectionScratch, pooled via
ScratchPool instead of one-per-virtual-thread (i.e. one-per-connection)
growth. The router's ThreadLocals are deliberately deferred to Phase 4
per this EX item's own phasing -- see DEC-15 for the plan-wording fix.
- EX-11: WebSocketSession.readFrame's extended-length and mask-key bytes
are now read in a single bounded readFully instead of one at a time.
- EX-12: full RFC 6455 frame validation -- continuation-frame
reassembly, mandatory masking-direction enforcement, opcode
validation, control-frame constraints (not fragmented, <=125 bytes),
and WebSocketProtocolException carrying the correct close code (1002
protocol error, 1009 message too big).
- EX-13: Connection header token-list scanning shared between the
keep-alive decision and the WebSocket upgrade check.
- EX-14: HEAD responses report Content-Length but write no body.
- EX-15: Content-Type omitted when empty; Content-Length and the body
omitted entirely for 204/304/1xx responses.
- EX-16: Date header (dev.relism.flash.http.DateHeader), refreshed once
per second by a shared daemon thread; FlashConfiguration.sendDate.
- EX-32: two-stage graceful shutdown -- stop accepting, force
Connection: close on the response an in-flight handler is still
producing (re-checked after the handler runs, not just before
dispatch, so a shutdown beginning mid-handler is still honoured),
drain up to shutdownDrainTimeoutMs, then force-close.
- EX-34: ServerHandle.create delegates to TransportFactory instead of
constructing HttpServer directly.
Two plan corrections recorded: DEC-15 (Phase 2's "no ThreadLocal
anywhere" DoD line contradicted EX-06's own multi-phase assignment --
corrected to match the registry) and DEC-16 (no separate
WebSocketFrameCodec class this phase; the EX-11/EX-12 fixes stay inside
WebSocketSession, which is one cohesive state machine under R6's own
carve-out -- revisit at Phase 15 if RFC 8441 needs the decoupling for
real).
HttpServer.java deleted.
311/311 tests green (flash module), run three times for stability of
the wall-clock-based timeout/shutdown tests. Whole-repo build green.
h1 benchmark regression check remains unverified in the plan's DoD (no
JMH harness until Phase 3, same caveat as Phase 1).

Fixes the request-smuggling and resource-exhaustion debt in the existing
HTTP/1.1 parser, and adds the ALPN/h2c-preface negotiation seam so a
connection's protocol is decided once, before any request is parsed, per
flash/docs/http2/IMPLEMENTATION-PLAN.md Phase 1.
Existing-code defects fixed (EX-nn):
- EX-02: reject Content-Length + Transfer-Encoding together (RFC 9112 6.1
CL.TE/TE.CL smuggling), and conflicting duplicate Content-Length values.
- EX-03: strict, overflow-safe Content-Length parsing, replacing a parser
that silently skipped non-digit bytes ("5abc" -> 5, "-1" -> 1).
- EX-07: header-read / idle-keep-alive / body-read timeouts enforced by an
absolute deadline (dev.relism.flash.transport.BufferedByteSource), not
merely Socket#setSoTimeout, which never trips against a peer trickling
one byte per read within the window.
- EX-08: header count / name length / value length / request-line length
bounds (Http1Limits), 431 on violation.
- EX-10: ChunkedInputStream now reads through BufferedByteSource instead
of the raw unbuffered socket stream, and the header-parser's read-ahead
bytes are handed over via a zero-copy prependOnce() instead of a
SequenceInputStream/ByteArrayInputStream pair.
- EX-17: HttpStatus's status-code bound is computed from values() instead
of a hand-maintained constant that silently threw
ArrayIndexOutOfBoundsException when a code above it was added; added
421, 431, 505, 507, 511 and others HTTP/2 and this hardening need.
- EX-18: bare-CR desync and obsolete line folding rejected.
- EX-30: the TLS handshake is forced explicitly, under a timeout, before
any protocol decision -- SSLSocket#getApplicationProtocol() returned
null until the handshake had run, and nothing previously forced it.
- EX-31: TLS 1.2 cipher suites on the RFC 9113 Appendix A blocklist are
filtered out of a listener's enabled set whenever it offers h2 via ALPN.
- EX-35 (found in this phase): Transfer-Encoding values listing multiple
codings ("gzip, chunked") were silently treated as not chunked at all,
corrupting the message boundary -- only the whole value was compared.
- EX-36 (found in this phase): a header line with no ':' was silently
skipped instead of rejected.
New:
- dev.relism.flash.transport.BufferedByteSource: the single buffered,
deadline-aware, peekable view over a connection's inbound bytes.
- dev.relism.flash.transport.ProtocolNegotiator/NegotiatedProtocol: ALPN
and h2c prior-knowledge detection. In this phase an H2 result is always
closed cleanly -- there is no Http2Connection to hand off to until
Phase 8. FlashConfiguration.http2Enabled gates the h2c preface peek.
- dev.relism.flash.exceptions.MalformedRequestException: a typed,
status-carrying rejection distinct from HttpException, caught at the
parse site so a malformed request never reaches the handler chain or
the user's exception handler, and the connection is always closed.
Two small plan-document corrections recorded as DEC-12 (Phase 1's Files
list omitted BufferedByteSource.java and MalformedRequestException.java;
the request-line-length check description pointed at the wrong offset).
DEC-13/DEC-14 record the deadline and exception-hierarchy designs.
277/277 tests green (flash module), run twice for stability of the new
wall-clock-based HttpServerTimeoutTest cases. Whole-repo build green.
h1 benchmark regression check is left unverified in the plan's DoD: no
JMH harness exists yet (Phase 3 deliverable).

Establishes the package layout, limits/error model and decision-log
convention that every later HTTP/2 phase depends on, per
flash/docs/http2/IMPLEMENTATION-PLAN.md Phase 0.
- dev.relism.flash.h2: package-info (architecture overview), Http2ErrorCode
(the 14 RFC 9113 §7 codes with precomputed 4-byte wire encodings),
Http2Exception (connection error -> GOAWAY) and Http2StreamException
(stream error -> RST_STREAM), neither extending IOException, both with
stack-trace capture disabled on the hot rejection path.
- Http2Limits: every bound Phase 0 requires (concurrent streams, frame
size, header list size, CONTINUATION/reset/settings/ping rate bounds,
flow-control windows, HPACK table size/string length, assembly and idle
timeouts), each documented with the attack or RFC clause it addresses.
- dev.relism.flash.http.Http1Limits: the h1 bounds needed by EX-03 (strict
Content-Length) and EX-08 (header count/size limits).
- flash/docs/http2/DECISIONS.md seeded with DEC-01..DEC-11 (the ten
decisions implied by the plan itself, plus DEC-11 recording that commits
keep scope `core` rather than adding `h2` to AGENTS.md).
- flash/docs/http2/IMPLEMENTATION-PLAN.md: added the Progress Ledger
(tracks phase status across sessions) and checked off Phase 0's DoD.
19 new tests, full flash module suite green (226/226).

Data/RepositoryFactory/HibernateData give applications one cached,
stateless entry point for repositories per entity type instead of
per-request instantiation, with write()/afterCommit() replacing manual
transaction+reload choreography.
McpConfig.rolesClaimPath is removed - MCP now derives the claim path
from OidcMiddleware.rolesClaimPath() so applications never duplicate
the roles-claim config between OIDC and MCP. McpPackageScanner is
rebuilt on the shared PackageScanner.discover(packageName) primitive,
doing only McpTool/McpResource/McpPrompt classification itself.

Adds the QUERY method (RFC 10008) — safe and idempotent like GET,
but carries a request body like POST, useful for complex filters
that don't fit in a URL query string.

- TlsConfig.applicationProtocols(String...) sets the listener's negotiable
ALPN protocol list via SSLParameters, inherited by every accepted socket
like clientAuth — works on both keystore() and ofContext(), untouched
unless called. Enables TLS-ALPN-01 (RFC 8737) style on-demand cert
issuance: a custom KeyManager can read the already-resolved protocol via
engine/socket getHandshakeApplicationProtocol() inside
chooseEngineServerAlias/chooseServerAlias, since ALPN is resolved during
ClientHello/ServerHello, always before Certificate production.
- Request gains isSecure()/sslSession(), threaded through RequestParser from
the accepted SSLSocket exactly like remoteAddress() — reference-only,
zero per-request allocation. sslSession() defers to SSLSocket#getSession()
lazily, so it's a cached-field read (handshake already completed by the
time a handler can call it), never a forced handshake.
- WebSocketSession.isSecure()/sslSession() delegate to the upgrading
Request rather than tracking the socket a second time.
- Documents TLS end-to-end in README.md (listeners, TlsConfig, SNI, ALPN,
mTLS, Request/WebSocketSession accessors).

Flash can now serve HTTPS and WSS, on one or many listeners per app:
- FlashConfiguration gains an optional `tls` field for the single default
listener, and a `listeners` list for apps that bind multiple ports (each
independently plain or TLS).
- New dev.relism.flash.tls package: TlsConfig.keystore(path, password) builds
an SSLContext from a PKCS12/JKS keystore, with SNI-based certificate
selection for free when the keystore holds more than one alias (matched by
SAN/CN, pure JDK APIs). TlsConfig.ofContext(sslContext) is a full escape
hatch — Flash never calls setSSLParameters on that path, so caller-set
protocols/cipher suites/ALPN survive untouched. TlsConfig.clientAuth(...)
adds optional/required mTLS on either path.
- HttpServer moves from a single ServerSocket to a list of bound listeners;
the per-request hot path (RequestParser, routing, response writing) is
untouched — TLS only changes which bytes come out of accept(), so WSS needs
no separate code path from WS.
- process()'s catch is widened to log non-IOException failures (e.g. a
misbehaving custom KeyManager/TrustManager on the ofContext path) instead
of swallowing them silently; the failure was already isolated to the one
connection via the existing try-with-resources/executor-submission
boundary — this only fixes the missing log line.
- Fixes a pre-existing gap where FlashConfiguration#host was accepted but
never used to bind (listeners always bound to the wildcard address).

- WebSocketSession supports client-mode outgoing frame masking (RFC 6455) via
in-place XOR, reusing the unmask routine already used for inbound frames.
- HeaderMap gains an allocation-free forEach(HeaderConsumer) for callers that
must handle an open-ended set of header names (e.g. proxying).
- HttpServer relays streaming/chunked response bodies through a shared
per-connection ThreadLocal buffer instead of relying on InputStream#transferTo
(which allocates internally) or a fresh byte[8192] per chunked write.
