Stefan Guilhen commented on JBAS-4654:
--------------------------------------
We don't have any NoSuchMethodExceptions being raised in the IIOP tests anymore, but that's probably because the root EJBException has been fixed. This means that JacORB can still behave badly when a non CORBA exception is thrown at server side because the org.jacorb.orb.SystemExceptionHelper is indeed erroneously assuming that all SystemExceptions have the same constructor, as Adrian already spotted.
Besides Adrian's suggestion of adding a catch clause for the NoSuchMethodException, another approach to solve this would be to change the SystemExceptionHelper.className() method to return org.omg.CORBA.UNKNOWN when a org.omg.CORBA.portable.UnknownException is received, as CORBA.UNKNOWN has the constructor JacORB is expecting. Regarding the original message, the problem is that even though UnknownException contains the root exception, this root exception is not written to the exception reply. As a result, when the exception is restored in SystemExceptionHelper, this information is no longer available. JacORB's UknownException has a constructor that also takes a message, so we could probably use it to inform the original message. I have to try this to see if it works.
Should we add another patch to our brewed JacORB to prevent NoSuchMethodExceptions?
