RFR [8038982]: java/lang/ref/EarlyTimeout.java failed again (original) (raw)

Hello!

The test EarlyTimeout.java failed again, now with message "elapsed time 981 is less than timeout 1000."

The root cause seems to be non-accurate time measurement in Windows: http://msdn.microsoft.com/en-us/library/windows/desktop/ms724397(v=vs.85).aspx

Because of this we can achieve this result: long start1 = System.currentTimeMillis(); long start2 = System.nanoTime();

~~~~~~~~ long elapsed2 = (System.nanoTime() - start2) / 1000000; long elapsed1 = System.currentTimeMillis() - start1;

assert elapsed2 < elapsed1; // can fail

There might be two ways to address the issue:

I did both.

Would you please help review the test fix?
