Hi Lori,
Thanks so much for the help! I was hoping we could at least catch the IllegalStateException so that it doesn't interrupt my execution. However this exception refuses to be caught. The first link you suggested (https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS72059) helped in changing the Exception (we are doing a similar thing with EPMDocumentMaster), but even the new WTRemoteException could not be caught.
Regards,
Sampurna
