Description/symptom of problem:  
PK30530 resolves the following problem:

ERROR DESCRIPTION:                                              
When "Exception Destination" is set to "None", the messages are 
incorrectly moved to System exception destination afterthe no.  
of retries are exhausted.                                       

LOCAL FIX:                                                      
The problem is due to the test on the exception destination     
field inmethod isBlockRequired in class                         
ExceptionDestinationHandlerImpl.java                            
checking for null whereas it should check for null or "".       

PROBLEM SUMMARY

USERS AFFECTED:
Users of WebSphere Application Server
versions 6.0.x and 6.1.x using default
messaging.

PROBLEM DESCRIPTION:
If an exception destination for a
destination is set to "" (a blank
field) using wsadmin, messages will
continue to be sent to the system
exception destination when they
should be left on the original
destination.

RECOMMENDATION:
None

A missing check for an empty field in the exception
destination setting for a destination resulted in messages
that should have remained on the destination being sent
to the system exception destination.

PROBLEM CONCLUSION:                                             
The fix adds a check for an empty field as well as null on the  
exception destination setting before sending messages to the    
system exception destination.
