Abstract:  nullpointerexception occurs after change to com.ibm.isecurityutilityimpl.passwordutil with was on ibm i

Description/symptom of problem:  
PH55723 resolves the following problem:

ERROR DESCRIPTION:
After updating to 9.0.5.16, a java.lang.NullPointerException    
occurs related to a change to                                   
com.ibm.ISecurityUtilityImpl.PasswordUtil with WAS on IBM i.    
This prevents the WAS v9.0 product and application servers from 
being managed in the IBM Web Administration for i web           
application on the IBM i OS. The same symptom was observed on   
other platforms in the thinclient scenarios.                    

LOCAL FIX:
Rollback to the 9.0.5.15 fix pack level or use the Qshell       
(STRQSH) IBM Installation Manager and WebSphere Application     
Server commands on the IBM i OS to manage your IBM WebSphere    
Application Server product.
