RE: [JBoss-user] OOM wrapped in UndeclaredThrowable
Yes, we throw UndeclaredThrowableException whenever a non-Exception shows up in an invocation stack as our interceptor signature allows for Exceptions, not Throwables or Errors. Search in our codebase for UndeclaredThrowableException and you'll see where this happens.

That is what I thought but if that would be the case wouldn't it be wrapped inside a InvocationTargetException? I than assumed it could maybe be caused by a dynamic proxy throwing this exception. Yet in case of a java.lang.Error it would actually not get wrapped in a UndeclaredThrowableException according to javadoc and my tests. Its possible that this is an exception marshalled back to a client and that the OOM is occuring on the server. Maybe a naïve question but, is there code in JBoss that would explicitly throw an UndeclaredThrowableException and stuff a marshalled exception inside it?
