ServerFailureRetrySingleOwnerTest doesn't actually test client retry -------------------------------------------------------------------- Key: ISPN-4903 URL: https://issues.jboss.org/browse/ISPN-4903 Project: Infinispan Issue Type: Bug Components: Server, Test Suite - Server Affects Versions: 7.0.0.CR2 Reporter: Dan Berindei Fix For: 8.2.0.Alpha1 Attachments: ServerFailureRetrySingleOwnerTest.java With {{useSynchronization = true}} (the default, before ISPN-4166 is integrated), the {{SuspectException}} thrown by the listener is swallowed by the transaction manager and the client doesn't retry. The test doesn't pick that up because the exception is thrown _after_ the entry was updated in the data container (a regular SuspectException would be thrown before). I changed the configuration to {{useSynchronization = false}}, but it didn't work because the {{SuspectException}} is wrapped in a {{CacheListenerException}}, so the client throws an exception instead of retrying. I also changed the test to use an interceptor instead of a listener, but then I got a {{ClassCastException}}: {noformat} Caused by: java.lang.ClassCastException: [B cannot be cast to org.infinispan.container.entries.CacheEntry at org.infinispan.cache.impl.CacheImpl.getCacheEntry(CacheImpl.java:424) at org.infinispan.cache.impl.CacheImpl.getCacheEntry(CacheImpl.java:429) at org.infinispan.server.hotrod.Decoder2x$.customReadKey(Decoder2x.scala:285) at org.infinispan.server.hotrod.HotRodDecoder.customDecodeKey(HotRodDecoder.scala:156) at org.infinispan.server.core.AbstractProtocolDecoder.org$infinispan$server$core$AbstractProtocolDecoder$$decodeKey(AbstractProtocolDecoder.scala:176) at org.infinispan.server.core.AbstractProtocolDecoder.decodeDispatch(AbstractProtocolDecoder.scala:71) ... 14 more {noformat}
