> In the context of Java Data Grid, when Infinispan detects [#write-skew] during prepare, it invokes [#setRollbackOnly]() on the transaction implementation. 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 that "invalid state" (of the transaction) is actually the cause of the failed commit. Only when debug logging was enabled could we see the root cause.
