During the deployment of an EAR I am getting the following exception. The same ear deploys fine in Jboss 4.2.3 however since upgrading to 5.1 the application no longer deploys correctly. I check the deployment descriptors (ejb-jar.xml and jboss.xml) but can't make any sense of this error messages.

org.jboss.deployers.spi.DeploymentException: Error deploying abc.jar: message destination name (/key) is null

Any suggestion to what this error refers and how I can it around it.
