Issue

• A module using JBoss EAP 5 jars is installed in JBoss EAP 7 in a similar way it was done to implement a login module. The objective is to use classes of the module from within an app (webapp) deployed in JBoss EAP 7 to call EJB's deployed in JBoss EAP 5 server which fails with the beloe exception :

java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "com.sun.proxy.$Proxy20.remove(Ljavax/ejb/Handle;)V" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, com/sun/proxy/$Proxy20, and the class loader (instance of org/jboss/modules/ModuleClassLoader) for interface javax/ejb/EJBHome have different Class objects for the type javax/ejb/Handle used in the signature
