IllegalArgumentException in VoidResponseCollector: Self-suppression not permitted --------------------------------------------------------------------------------- Key: ISPN-12710 URL: https://issues.redhat.com/browse/ISPN-12710 Project: Infinispan Issue Type: Bug Components: Core Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 12.1.0.Final, 12.0.1.Final Since the ISPN-12662 fix {{ConsistentReliabilitySplitBrainTest.testLockUseAfterPartitionWithMajority}} is failing in CI: {noformat} 16:24:32,401 ERROR (testng-Test:[]) [TestSuiteProgress] Test failed: org.infinispan.lock.ConsistentReliabilitySplitBrainTest.testAutoReleaseIfLockIsAcquiredFromAMinorityPartition[DENY_READ_WRITES] java.lang.Error: java.util.concurrent.ExecutionException: org.infinispan.lock.exception.ClusteredLockException: org.infinispan.remoting.RemoteException: ISPN000217: Received exception from Test-NodeD, see cause for remote stack trace at org.infinispan.functional.FunctionalTestUtils.await(FunctionalTestUtils.java:67) ~[infinispan-core-12.1.0-SNAPSHOT-tests.jar:12.1.0-SNAPSHOT] at org.infinispan.lock.ConsistentReliabilitySplitBrainTest.testAutoReleaseIfLockIsAcquiredFromAMinorityPartition(ConsistentReliabilitySplitBrainTest.java:133) ~[test-classes/:?] {noformat} That fix replaced a usage of {{MapResponseCollector}} with {{VoidResponseCollector}}, which makes sense because the response values are ignored. The problem is that {{VoidResponseCollector}} tries to keep track of the exceptions received from all the targets by adding them as suppressed exceptions to the first received exception, and {{ThrowableExternalizer}} reuses {{OutdatedTopologyException}} instances, causing an {{IllegalArgumentException}}: {noformat} 16:24:32,380 ERROR (jgroups-12,Test-NodeD:[]) [InvocationContextInterceptor] ISPN000136: Error executing command ReadWriteKeyCommand on Cache 'org.infinispan.LOCKS', writing keys [ClusteredLockKey{name=Test}] java.lang.IllegalArgumentException: Self-suppression not permitted at java.lang.Throwable.addSuppressed(Throwable.java:1066) ~[?:?] at org.infinispan.remoting.transport.impl.VoidResponseCollector.recordException(VoidResponseCollector.java:54) ~[infinispan-core-12.1.0-SNAPSHOT.jar:12.1.0-SNAPSHOT] at org.infinispan.remoting.transport.impl.VoidResponseCollector.addException(VoidResponseCollector.java:46) ~[infinispan-core-12.1.0-SNAPSHOT.jar:12.1.0-SNAPSHOT] at org.infinispan.remoting.transport.impl.VoidResponseCollector.addException(VoidResponseCollector.java:18) ~[infinispan-core-12.1.0-SNAPSHOT.jar:12.1.0-SNAPSHOT] at org.infinispan.remoting.transport.ValidResponseCollector.addResponse(ValidResponseCollector.java:29) ~[infinispan-core-12.1.0-SNAPSHOT.jar:12.1.0-SNAPSHOT] at org.infinispan.remoting.transport.impl.MultiTargetRequest.onResponse(MultiTargetRequest.java:92) [infinispan-core-12.1.0-SNAPSHOT.jar:12.1.0-SNAPSHOT] at org.infinispan.remoting.transport.impl.RequestRepository.addResponse(RequestRepository.java:51) [infinispan-core-12.1.0-SNAPSHOT.jar:12.1.0-SNAPSHOT] at org.infinispan.remoting.transport.jgroups.JGroupsTransport.processResponse(JGroupsTransport.java:1407) [infinispan-core-12.1.0-SNAPSHOT.jar:12.1.0-SNAPSHOT] {noformat}
