Problem Summary

PQ80441 - Transaction recovery can fail when a server is        
restarted, or a NullPointerException may be thrown when        
recovering distributed transactions.                            
                                                               
PQ81390 - 1. A security exposure was discovered in the 5.1      
release related                                                
to how the LTPA token handles expiration. When the token        
gets validated, it gets a new expiration, even if expired.      
2. When security trace is enabled nulpointer exception might be
raised.                                                        

Problem Conclusion

PQ80441 - Transaction recovery can fail when a server is        
restarted, or a NullPointerException may be thrown when        
recovering distributed transactions.                            
                                                               
PQ81390 - The token no longer gets a new expiration when it is  
validated if it is expired.
