TEST_PING doesn't trigger merge after JGroups 4.0.13 upgrade ------------------------------------------------------------ Key: ISPN-9483 URL: https://issues.jboss.org/browse/ISPN-9483 Project: Infinispan Issue Type: Bug Components: Test Suite - Core Affects Versions: 9.4.0.CR1 Reporter: Dan Berindei Assignee: Dan Berindei Labels: testsuite_stability Fix For: 9.4.0.CR3 In JGroups 4.0.13.Final, {{MERGE3}} started using the {{ASYNC_DISCOVERY_EVENT}} to find other members. {{TEST_PING}} doesn't handle the event correctly, at least when trace logging is enabled, and the merge never happens. {{Discovery}} should handle the new event automatically, but it only works if the discovery protocol actively sends out {{GET_MBRS_REQ}} messages and receives {{GET_MBRS_RSP}} messages from other members. {{TEST_PING}} doesn't receive any {{GET_MBRS_RSP}} messages, so {{Discovery.addResponse()}} is never called. This causes failures in all the tests that split the cluster and heal it, but for some reason CI isn't reporting the failures: {noformat} [OK: 70, KO: 1, SKIP: 0] Test failed: org.infinispan.distribution.rehash.RehashAfterPartitionMergeTest.testCachePartition[DIST_SYNC] java.lang.RuntimeException: Timed out before caches had changed views ([[RehashAfterPartitionMergeTest[DIST_SYNC]-NodeB-45390], [RehashAfterPartitionMergeTest[DIST_SYNC]-NodeD-46782]]) to contain 2 members at org.infinispan.test.TestingUtil.blockUntilViewsChanged(TestingUtil.java:761) at org.infinispan.test.TestingUtil.blockUntilViewsChanged(TestingUtil.java:743) at org.infinispan.distribution.rehash.RehashAfterPartitionMergeTest.testCachePartition(RehashAfterPartitionMergeTest.java:67) {noformat} https://ci.infinispan.org/job/Infinispan/job/master/808/consoleFull
