java/util/concurrent/locks/Lock/TimedAcquireLeak.java test timeouts in 2016-04-28 hs nightly on all platforms except Windows. On Windows test passed.

I was able to reproduce it locally on my Linux-x64. Test executed successfully with 2016-04-27 hs nightly binary, but fails with 2016-04-28 hs nightly binary.

Log contains information about IllegalStateException:
----------System.out:(1/38)----------
Timeout signalled after 1,920 seconds
----------System.err:(15/1068)----------
