Injection of an EJB from a separate application results in a NullPointerException

When an EJB in injected via the @EJB annotation from a separately deployed jar (i.e., the injected EJB is not in the same jar or same ear as the @EJB annotated EJB) and the mappedName attribute is not specified, a NPE results on deployment.. This exception should be replaced with a more appropriate, and informative exception.
