EJB chain failed to commit the distributed XA transaction if the EJB's are deployed on more than 2 EAP7 servers

Issue

• If an application is using several different servers, the invocation seems correct but the final commit of the XA transaction will fail with WFTXN0034, JBREM000308, ARJUNA016027, ARJUNA016009, ARJUNA016045. If the applications are all deployed to the 2nd server, then the use-case works fine.

• Transaction recovery fails and throws an Exception if applications are deployed on different instances:
