RFR: 8376479: Http3 test server thread deadlock in ThrowingPublishersInRequest

Tue Jan 27 14:01:58 UTC 2026

This fixes a deadlock between the thread that reads from the RequestBodyInputStream and the thread that tries to close it in response to a stream reset. See the linked JBS ticket for details.

Tier1 and tier2 tests continue to pass. I verified that with this change there are no busy threads at the end of the test.
