RFR: 8376089: Increase QUIC idle timeout in H3FixedThreadPoolTest to collect more diagnostic

Thu Jan 22 10:30:53 UTC 2026

This test failed on Tier 7, but the failure could not be reproduced. Increase the QUIC idle timeout to a value higher than the JTreg on Tier 7 so that, if the client becomes wedged again, the JTreg timeout handlers can collect more diagnostic information.
