There are 2 issues related to test/java/util/Arrays/ParallelPrefix.java,
1. JDK-8080165, which is marked as samebinary-highfrequency. Based on
below information, I think this bug should have been resolved, although
I don't know which change set resolve the issue,
1. the last failure happened more than one year before;
2. run 3 loops concurrently, in every loop run ParallelPrefix 1000 times
sequentially, PrefixBug(Paul's reproducible code above) is run in below
mode on jdk9-b128:
java -server -XX:LoopUnrollLimit=0 -XX:TieredStopAtLevel=4 PrefixBug
java -server -XX:LoopUnrollLimit=0 PrefixBug
java -server PrefixBug
3. issue easily reproduced by build/run "javac/java PrefixBug" on jdk9-b64.
2. JDK-8085982, which is not reproduced.
So, I think ParallelPrefix.java should be removed from ProblemList.txt
