ClassNotFoundException raised by PeriodicRecovery thread for resource adapter in EAP 6

Issue

• A custom resource adapter contains multiple JAR files deployed in a single module
• A JNDI bound resource is accessed from a resource adapter when periodic recovery calls getXAResources()
• The bound resource is of a class which is not in the same JAR as the resource adapter implementation class
• A ClassNotFoundException is raised and recovery fails

... java.lang.ClassNotFoundException: my.jndi.bound.CtxFactory from [Module "org.jboss.jts:main" from local module loader ...]
