Hi Team,

Getting below error in Junit testcase for comparator.

Caused by: java.lang.IllegalArgumentException: Comparison method violates its general contract!
at java.util.TimSort.mergeHi(TimSort.java:899)
at java.util.TimSort.mergeAt(TimSort.java:516)
at java.util.TimSort.mergeForceCollapse(TimSort.java:457)
at java.util.TimSort.sort(TimSort.java:254)
at java.util.Arrays.sort(Arrays.java:1438)
at java.util.List.sort(List.java:478)
at java.util.Collections.sort(Collections.java:175)

While using below VM argument, it is working fine - For JDK 1.8.
-Djava.util.Arrays.useLegacyMergeSort=true

But the same is failing in Open JDK 1.8.

Thanks in Advance!
