Error message

bandwidth exceeded

What it means

responseStatusException throws Spring's ResponseStatusException with HttpStatus.BANDWIDTH_LIMIT_EXCEEDED (529) and reason 'bandwidth exceeded'. The test verifies Quarkus maps ResponseStatusException to the annotated HTTP status and reason string automatically, without a custom mapper.

Solutions

1. Assert the client receives HTTP 529 and the 'bandwidth exceeded' reason; if not, check the RESTEasy Reactive version's ResponseStatusException handling.
2. If you intended a different status, adjust the HttpStatus passed in the test or the test assertion.
3. Confirm no custom mapper overrides ResponseStatusException handling in the test app.

Response r = given().when().get("/exception/responseStatusException");
if (r.getStatusCode() != 529)
    throw new AssertionError("ResponseStatusException status not honored: " + r.getStatusCode());

When it happens

Trigger: GET /exception/responseStatusException invokes responseStatusException which always throws ResponseStatusException(BANDWIDTH_LIMIT_EXCEEDED, "bandwidth exceeded").

Common situations: Appears when testing default ResponseStatusException handling; failures mean the framework no longer honors the status/reason, e.g. after a RESTEasy Reactive upgrade.
