Standard jakarta.validation annotations, compiled once per type into a flat
check table. No configuration: constraints come from the annotations already on
your types, and ValidationException extends HttpException with status 422 so
the default handler renders it without this extension registering anything.
record CreateUser(@NotBlank @Size(max = 80) String name,
@Email String email,
@Min(18) int age) {}
CreateUser dto = validation.body(req, CreateUser.class);
Annotations only — Hibernate Validator's engine is deliberately absent. It
resolves constraints reflectively per call and pulls ~2 MB plus EL, which is
the per-request cost this module exists to avoid. jakarta.validation-api is
~90 KB of annotations.
The passing path allocates nothing. Constraints resolve at first use into an
opcode plus operands cached in a ClassValue, so there is no map lookup and no
lock. Fields are read through MethodHandles adapted to an exact signature —
(Object)Object for references, (Object)long for primitive integrals — so
invokeExact neither boxes nor builds the argument array Field.get and
Method.invoke allocate. Checks are a flat array walked by a tableswitch rather
than a class hierarchy behind a virtual call. @Size reads a length the object
already knows and @Email scans with indexOf, because Pattern.matcher allocates
a matcher and two int arrays per call. Messages are pre-rendered at compile
time. The violation list and the exception exist only once something fails.
@Pattern is the marked exception: its regex compiles once but matcher()
allocates per call.
Constraints are read from declared fields, so records and plain classes take
one code path — a constraint on a record component propagates to its backing
field.
Jakarta null semantics are exact: only @NotNull rejects null.
flash-ext-openapi now mirrors the same annotations into the generated schema —
minLength, maxLength, minItems, minimum, maximum, pattern, format: email and
required — via an optional jakarta.validation dependency detected at boot. A
type declares its rules once and both the validator and the published contract
read them. An explicit @Schema still wins; the bridge only fills keys nobody
set, and without the annotations on the classpath the bridge class is never
loaded.
flash-ext-jackson is optional too: validate(value) works without it, only
body(req, type) needs a codec.

No maven-deploy-plugin skip here (there used to be one): flash-extensions is a
|
|
pom-packaging aggregator with no jar of its own, but every flash-ext-* submodule's
|
|
effective POM inherits from it via <parent> — skipping its deploy meant remote consumers
|
|
(anything resolving a flash-ext-* artifact from Gitea's Maven registry rather than a
|
|
local ~/.m2 install) couldn't resolve that parent POM at all. See

pathway/.gitea/workflows/docker-build.yml and pathway/docs/CI-CD.md.
