Hi Apurva,
Even though it supports Java 7 be careful with the following.
In Java 7, Oracle changed the “modified mergesort” in java.util.Arrays.sort with timsort: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=6804124 A full description of this change can be found here: http://dertompson.com/2012/11/23/sort-algorithm-changes-injava-7/
In Version 6.x PRPC systems, this now causes Obj-Sort to fail with a Java error: “Caused by: java.lang.IllegalArgumentException: Comparison method violates its general contract!” To avoid this error, set the following Java System property when using Java 7 with PRPC 6.x: - Djava.util.Arrays.useLegacyMergeSort=true
