Hi everyone,

I'm looking for a couple of review for a simple change in test: -Xmx128m 
-> -Xmx256m

http://cr.openjdk.java.net/~dfazunen/8169643/webrev.00/
https://bugs.openjdk.java.net/browse/JDK-8169643

The GCBasher test fails with OOM if run with -XX:-UseCompressedOpps.
The root cause is 128Mb is not enough to locate a big structure if Opps 
are not compressed.
Giving more memory fixes the problem (TestGCBasherWithParallel.java 
specifies 256m and doesn't fail)

Thanks,
Dima
