             Summary: Infinispan calling setRollbackOnly() when detecting write skew
                 Key: ISPN-5927
                 URL: https://issues.jboss.org/browse/ISPN-5927
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 6.0.2.Final
            Reporter: Stephen Fikes


In the context of Java Data Grid, when Infinispan detects write skew [#write-skew] during prepare, it invokes {{setRollbackOnly()}} on the transaction implementation [#set-rollback]. This results in an exception ({{com.arjuna.ats.jta.exceptions.InvalidTerminationStateException: ARJUNA016064: The transaction is in an invalid state!}}) because this operation is disallowed by Arjuna while in the {{PREPARING}} state. The result is that the causal error ({{org.infinispan.transaction.WriteSkewException}}) is lost and the error that propagates indicates the "invalid state" is actually the cause of the failed transaction.
