RFR 8079353: [TESTBUG] runtime/CompressedOops/UseCompressedOops.java failed on Windows when getting disjoint instead of zero based coops

[Harold Seigel]

Hi,

Please review this fix for JDK-8079353.  The fix excludes the sub-tests 
that may fail on Windows because of ASLR.  The webrev also has some 
small test cleanup.

Open Webrev: 
http://cr.openjdk.java.net/~hseigel/bug_8079353/webrev/index.html

Open JBS:  https://bugs.openjdk.java.net/browse/JDK-8079353

The fix was tested by running it 500+ times on Windows without a 
failure.  Additionally, the test was regression tested on Linux, Mac, 
and Solaris.

Thanks, Harold
