Please, review the following test change Issue : https://bugs.openjdk.java.net/browse/JDK-8064441 Webrev: http://cr.openjdk.java.net/~jbachorik/8064441/webrev.00
The test fails because of System.out.println() may induce unexpected locking. The solution is to use an already existing LockFreeLogManager library class to collect the logs in the lock-free manner and print the logs only after all the test code has been run.
