Sometimes the ejb3 error message are incomprehensible. You've got no idea which ejb or even deployment it is referring to. For now I've added a couple of DeploymentException wrappings which at least narrows down where you need to look. But this should not be necessary. The error message should always include some context on what it is working with. Doing so will avoid this horrible exception wrapping, e.g. | 17:13:54,239 ERROR [AbstractKernelController] Error installing to Real:
