Continuing the conversation about:
https://bugs.openjdk.java.net/browse/JDK-8078672
with an updated patch:
http://cr.openjdk.java.net/~bpb/8078672/webrev.01/.
Please review at your convenience.
Summary:
1) test/java/lang/RandomFactory.java is moved to test/lib/testlibrary/jdk/testlibrary/ (with respect to the previous patch but not visible in the webrev) and getSplittableRandom() is added.
2) the java/lang/{Double,Integer,Long,Math} tests modified in the previous patch are updated to use RandomFactory in its new, generic location.
3) the java/math/Big{Decimal,Integer} tests which used test/java/math/RandomSeed are modified to use RandomFactory.
4) test/java/math/RandomSeed.java is removed.
All tests pass locally on OS X and a job testing jdk_lang and jdk_math has been submitted to the usual set of platforms.
Thanks,
Brian
