RFR 6963841: java/util/concurrent/Phaser/Basic.java fails intermittently

[Chris Hegarty]

David, Doug,

This test has been failing intermittently on jdk7u-dev and jdk8 for a 
while now. It only appears to fail when run in our internal build/test 
system (JPRT).

I believe the cause of the failure to be simply that the machines the 
test is run on are too slow, or very busy, and the defensive timeout in 
the test are not large enough to handle this. The solution is to 
increase these timeout (similar to other tests in the concurrency area 
that we increased the timeouts for too).

Thanks,
