java/lang/Thread/ThreadStateTest.java can fail with when
checkThreadState finds an unexpected state.
Exception in thread "main" java.lang.RuntimeException: MyThread expected
to have TERMINATED but got RUNNABLE
at ThreadStateTest.checkThreadState(ThreadStateTest.java:119)
at ThreadStateTest.main(ThreadStateTest.java:96)
There is a race between the thread being put in a specific state and the
thread testing for that state. The test should retry the thread state
check a number of times before failing. Also, some minor cleanup and
update to use a more recent j.u.c reusable synchronization barrier.
