public class StatsBugDUnitTest
extends DistributedTestCase

This is Dunit test for bug 36109. This test has a cache-client having a primary and a secondary cache-server as its endpoint. Primary does some operations and is stopped, the client fails over to secondary and does some operations and it is verified that the 'invalidates' stats at the client is same as the total number of operations done by both primary and secondary. The bug was appearing because invalidate stats was part of Endpoint which used to get closed during fail over , with the failed endpoint getting closed. This bug has been fixed by moving the invalidate stat to be part of our implementation.
