[9] RFR of 8078586: java/lang/Double/ParseHexFloatingPoint.java fails intermittently

[Brian Burkhalter]

Please review at your convenience.

Issue:	https://bugs.openjdk.java.net/browse/JDK-8078586
Patch:	http://cr.openjdk.java.net/~bpb/8078586/webrev.00/

Summary: Add setting of Random seed via system property with fallback to a random seed from a separate Random instance and printing the seed actually used in the test.

The question is whether this change should be made under JDK-8078586 which is better resolved as “Cannot Reproduce” given its 0.07% failure rate, or whether a separate issue should be filed for these test changes.

Thanks,

Brian
