[jacorb-developer] java.lang.OutOfMemoryError silently caught by JacORB

Nick,
I do not have simple test case yet that I can supply, that would take a bit of work. The client is a fairly large java application that uses JacORB, the server is a fairly large C++ application that uses OmniOrb. I would need to create something that duplicates this particular situation, asking for a large sized piece of data.
It seems that the problem is that somewhere there is a:
catch (Throwable t)
that is swallowing the OOM, things do not crash, eventually a CORBA.TIMEOUT occurs, but the user of the application does not know why the timeout occurred.
Regards,
Eric

Are you able to provide a test case? I think the problem here is isolating OOM from the JVM and being able to recover and transmit the error to the client.

Some time later a CORBA timeout is thrown, so that the user knows something went wrong, but since the uncaught exception handler in the application did not catch the initial error, we do not automatically know to instruct the user to increase the -Xmx setting, which corrects the problem.
