The constraint compiler ignored the message an annotation declares and always wrote its own, so a failed @Pattern answered the caller with a regex.

It now uses the annotation's message whenever one is set, keeping the plain description for jakarta's default — which is a resource bundle key, not something to put in front of whoever sent the request.

@Pattern(regexp = "[A-Za-z0-9_][A-Za-z0-9_.-]{0,254}", message = "uses up to 255 letters, digits, _, . and -")

{"error": "key uses up to 255 letters, digits, _, . and -", "status": 422}

This is what makes moving a check out of a service and onto the type it belongs to cost nothing: the wording moves with it.

The compiler ignored the message a constraint declares and always wrote its
own, so a failed @Pattern answered the caller with a regex. It now uses the
annotation's message whenever one is set, and keeps the plain description for
jakarta's default, which is a resource bundle key and not something to put in
front of whoever sent the request.

This is what makes moving a check out of a service and onto the type it
belongs to cost nothing: the wording moves with it.
