[8u-dev] Review request : JDK-8068416: LFGarbageCollectedTest.java fails with OOME: "GC overhead limit exceeded"

[Konstantin Shefov]

Igor,

It seems I have given you wrong information. This test fails with OOME 
against JDK 9 also, I managed to reproduce the failure now.
It was hard to reproduce it because of randomness, I need to rerun the 
test 50 times. Although the test seems to fail with OOME more often 
against JDK 8u, but I think it is just factor of randomness in the test.

So I do not think it is a product bug then.
