I got the following Log message:
Unsupported Exception: class java.lang.reflect.InvocationTargetException
This is caused by line 112 in DispositionReportFaultMessage:
log.error("Unsupported Exception: " + e.getClass());
Please change it so it outputs the exception stacktrace and unwrap InvocationTargetException. I had to actually remote debug the application to get the actual error message...
