A NullPointerException appears while processing the 2nd tx:

{noformat}
04:27:12,078 DEBUG (remote-thread-ReplTotalOrderVersionedStateTransferTest-NodeB-p12450-t4:) [TotalOrderInterceptor] Exception while rollback transaction ReplTotalOrderVersionedStateTransferTest-NodeC-12055:56786

{noformat}

(The error message is misleading, this is a commit and not a rollback.)

The 1st tx still fails with a WriteSkewException, but then the test fails because the 2nd tx didn't update the value:

{noformat}
04:27:12,286 ERROR (testng-ReplTotalOrderVersionedStateTransferTest:) [UnitTestTestNGListener] Test testStateTransfer(org.infinispan.tx.totalorder.statetransfer.ReplTotalOrderVersionedStateTransferTest) failed.
