RFR 8076050: java/lang/management/ThreadMXBean/ThreadMXBeanStateTest.java fails intermittently

[Jaroslav Bachorik]

Please, review the following test change

Issue : https://bugs.openjdk.java.net/browse/JDK-8076050
Webrev: http://cr.openjdk.java.net/~jbachorik/8076050/webrev.00

This is another intermittently failing test due to timing problems.

The test thread is requested to move to "TIMED_WAITING" state and the 
main thread then performs the asserts. The test thread will stay in 
"TIMED_WAITING" state 10s (lock.wait(10000) in 
test/java/lang/Thread/ThreadStateController.java#168) and after this 
timeout it moves on. The wait may be cancelled by the main thread after 
it has performed the asserts.

This timeout might turn out insufficient. The proposed solution is to do 
`lock.wait(Integer.MAX_VALUE)` instead. Aside of this change I also 
introduced the usage of `Utils.adjustTimeout(timeout)` to adjust the 
requested timeouts to the test timeout scaling factor.

The change in 
test/java/lang/management/ThreadMXBean/ThreadMXBeanStateTest.java is 
purely for the purpose of improving the log output - currently, when the 
test fails the output is ignored; and this was fixed.


Thanks,
