<Sound Dev> [9] Review Request: 8148915: Intermittent failures of bug6400879.java

[Sergey Bylokhov]

Hello, Audio Guru.

Please review the small fix for unstable test reported by mach5 in jdk9.
The test has two issues:
  - It uses System.currentTimeMillis() which can be affected by the 
system time change. Replaced by System.nanoTime().
  - It maintains its own timeout(5 seconds) to catch the hang of the 
test. It was found that on some overloaded system this period is not 
enough(on the tested system was necessary to increase it to 30-40 
seconds or it will fail a few times per 1000 executions). I removed this 
internal timeout from the test(it is provided as the warning now), and 
relies on jtreg default timeout. It has a benefit that when the test 
hangs the jtreg will provide a jstack output which will be useful to 
understand where is the problem.
