java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling ... on remote EAP6 client when threads sharing context

Issue

• I have an standalone application which running that creates threads to make some tasks, which calls EJBs in JBoss EAP 6. We hold the initialContext object and it is never destroyed, so it keeps the connection alive.
