How about moving | if (th instanceof InvocationTargetException) | { | // Unwrap the throwable raised by the service endpoint implementation | Throwable targetEx = ((InvocationTargetException)th).getTargetException(); | handleInvocationException(targetEx); | } | to native and only unwrap the MBeanException as part of the SPI.
