NPE thrown by RemoteTransaction
-------------------------------

                 Key: ISPN-724
                 URL: https://jira.jboss.org/browse/ISPN-724
             Project: Infinispan
          Issue Type: Bug
            Reporter: Changgeng Li
            Assignee: Manik Surtani
            Priority: Critical
             Fix For: 4.2.0.BETA1


Using the current snapshot build in our product I got  a lot of NPE. 

I'm not able to reproduce it in unit test, but from the stack trace, I can see it may related with fix to ISPN-711.
