> Thread::getState is an API for monitoring and management purposes to report > the thread state. If a virtual thread is parked with LockSupport.parkNanos, > its state is reported as WAITING when it should be TIMED_WAITING. JVM TI > GetThreadState has the same issue in that it returns > JVMTI_THREAD_STATE_WAITING_INDEFINITELY instead of the > JVMTI_THREAD_STATE_WAITING_WITH_TIMEOUT bit set. Not a very visible issue > because JDWP maps both states to "WAIT" but it may be noticed by tools using > other JVM TI agents. > > The change is straight-forward, it's just additional bit to indicate that the > parking/parked/pinned states are timed. The existing virtual/ThreadAPI.java > test is expanded to this scenario. A new test is added for JVM TI > GetThreadState to test waiting/timed-waited cases (including pinned) as test > coverage seems patchy here.
