        Description

        TESTFAIL:java/util/concurrent/locks/ReentrantLock/CancelledLockLoops.java

        The following test:

        java/util/concurrent/locks/ReentrantLock/CancelledLockLoops.java

        failed with message:

        java.lang.Error: Completed != 2
        at CancelledLockLoops$ReentrantLockLoop.test(CancelledLockLoops.java:119)
        at CancelledLockLoops.main(CancelledLockLoops.java:65)

        at java.lang.Thread.run(Thread.java:713)

        Unfortunately, the test does not print the 'completed' variable value.

        It's not clear if it is a test bug or bug in the java.util.concurrent library. The bug seems to occur rarely. I was not able to reproduce it.

        Possible product bugs:
         - Thread.interrupt() was not delivered to a thread
         - Variable named 'completed' was not shared with other threads after update and lock.unlock() operation
         - other reasons??

        Possible test bugs:
         - one of the test threads managed to complete before the test interrupted it (at line 98)
