Description Roman Dawydkin CLA 2011-07-29 07:19:45 EDT 
Build Identifier: I20110613-1736

Running Eclipse 3.7 under JDK7, when installing new software (specifically Java 7 support patches from "http://wiki.eclipse.org/JDT/Eclipse_Java_7_Support_%28BETA%29"), exception occurs:
java.lang.IllegalArgumentException: Comparison method violates its general contract!
Stack trace will be attached.
Switching to legacy sort with VM option -Djava.util.Arrays.useLegacyMergeSort=true installation works OK.



Reproducible: Always
