When a virtual thread is mounted, the carrier thread should be reported as "waiting" until the virtual thread unmounts. Right now, GetThreadState reports a state based the JavaThread status when it should return JVMTI_THREAD_STATE_WAITING | JVMTI_THREAD_STATE_WAITING_INDEFINITELY. The fix adds: - a special case for passive carrier threads - necessary test coverage to the existing JVMTI test: `serviceability/jvmti/vthread/ThreadStateTest`.
Testing: - tested with the updated test: `serviceability/jvmti/vthread/ThreadStateTest` - submitted mach5 tiers 1-5 - TBD: to submit mach5 tier 6 ------------- Commit messages: - minor tweaks in libThreadStateTest.cpp - 8307153: JVMTI GetThreadState on carrier should return STATE_WAITING Changes: https://git.openjdk.org/jdk/pull/14298/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14298&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8307153 Stats: 71 lines in 4 files changed: 61 ins; 0 del; 10 mod Patch: https://git.openjdk.org/jdk/pull/14298.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14298/head:pull/14298 PR: https://git.openjdk.org/jdk/pull/14298
