             Summary: 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: 7.0.0.Final


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}}:
