Abstract:  StackOverflowError during deserialization of a Web Service definition

Description/symptom of problem:  1) Symptom:
   --------
   
A StackOverflowError might occur during the installation of an enterprise application containing a business process or when an activity that calls a Web Service is executed. The error can look like this:

   com.ibm.bpe.api.EngineUncaughtExceptionInProcessException: BPEE0002E: 
   Uncaught exception in process '_PI:300fb.4d8a8b50.d0b6ef6.0'.
   com.ibm.bpe.api.EngineUncaughtExceptionInActivityException: BPEE0001E: 
   Uncaught exception in activity 'getWorkOrderTasks'.
   com.ibm.bpe.api.EngineImplementationInvocationException: BPEE0003E: 
   An error occurred during the invocation of the activity implementation 'null'.
   com.ibm.bpe.api.ProcessError: Error during Deserialization
   java.lang.StackOverflowError

2) Problem:
   --------
   
Under rare circumstances the Web Service definition can be so complicated that it leads to the StackOverflowError in the Java default deserialization mechanism.
   
3) Solution:
   ---------

With this interim fix the default for the serialized format of the 
Web Service definition is changed so that this error does not occur. 
Your installed business processes are not affected by this fix; they can be executed without any changes. If you have had this error, uninstall the enterprise application that caused the problem and install the enterprise application again after you apply the interim fix.


Directions to apply fix:

NOTE:  FIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.  DO NOT REMOVE A FIX UNLESS
     ALL FIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY REAPPLY ANY REMOVED FIX.

Example:  If your system has fix1, fix2, and fix3 applied in that order and fix2 is to be
          removed, fix3 must be removed first, fix2 removed, and fix3 re-applied.
