Parameterizable EJB transaction timeout being overridden in JBoss EAP 6

Issue

• The transaction timeout period has been configured on two servers to be greater than 300 seconds (e.g. 5400 seconds)
• A remote call from one server to the other takes more than 5 minutes and the global transaction is timed out
  • The timeout imposed on the remote call seems to be hardcoded to 300 seconds (5 minutes)
  • The specified remote client transaction timeout values are overwritten
