Darrel Schneider edited comment on GEODE-1137 at 5/10/16 12:25 AM: ------------------------------------------------------------------- This looks like a bug in the test; not in the product. Note that the failure is caused by this cast exception: Caused by: java.lang.ClassCastException: com.gemstone.gemfire.internal.cache.GIIDeltaDUnitTest$32$1 cannot be cast to com.gemstone.gemfire.internal.cache.GIIDeltaDUnitTest$BlockMessageObserver at com.gemstone.gemfire.internal.cache.GIIDeltaDUnitTest.resetSlowGII(GIIDeltaDUnitTest.java:2544) at com.gemstone.gemfire.internal.cache.GIIDeltaDUnitTest.lambda$preTearDownCacheTestCase$84651174$1(GIIDeltaDUnitTest.java:113) This test method has code that calls DistributionMessageObserver.setInstance twice with calls that would have set it to an instance of GIIDeltaDUnitTest$32$1. If these end up not getting cleaned up before tear down then the unconditional call of resetSlowGII will result in this class cast exception. was (Author: dschneider): This looks like a but in the test; not in the product.
