[infinispan-issues] [JBoss JIRA] (ISPN-6792) NonTxDistributionInterceptor doesn't always change the matcher for retry

NonTxDistributionInterceptor doesn't always change the matcher for retry ------------------------------------------------------------------------ Key: ISPN-6792 URL: https://issues.jboss.org/browse/ISPN-6792 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.0.0.Alpha2, 8.2.2.Final Reporter: Dan Berindei Assignee: Dan Berindei Labels: testsuite_stability Fix For: 9.0.0.Alpha3 When invoking a non-transactional write command remotely, {{BaseDistributionInterceptor}} expects to receive an {{OutdatedTopologyException}} wrapped in a {{RemoteException}} if the remote node saw a newer cache topology. However, {{OutdatedTopologyException}} is handled differently by {{JGroupsTransport}}, and it is *not* wrapped in a {{RemoteException}}. Because of this, {{BaseDistributionInterceptor}} doesn't update the value matcher, and the retried command may fail when it sees its own value. This makes {{NonTxPutIfAbsentDuringLeaveStressTest}} fail randomly with {noformat} java.lang.AssertionError: expected:<null> but was:<value_7_0> at org.testng.AssertJUnit.fail(AssertJUnit.java:59) at org.testng.AssertJUnit.failNotEquals(AssertJUnit.java:364) at org.testng.AssertJUnit.assertEquals(AssertJUnit.java:80) at org.testng.AssertJUnit.assertEquals(AssertJUnit.java:88) at org.infinispan.distribution.rehash.NonTxPutIfAbsentDuringLeaveStressTest.testNodeLeavingDuringPutIfAbsent(NonTxPutIfAbsentDuringLeaveStressTest.java:101) {noformat} Note that this is different from ISPN-6451: there, the assertion message is {{AssertionError: expected:<value_48_1> but was:<null>}}, and it is most likely caused by ISPN-3918.
