PROBLEM SUMMARY

USERS AFFECTED:
 IBM WebSphere Application Server users of
JAX-WS web services.

PROBLEM DESCRIPTION:
java.lang.NullPointerException issue
when starting multiple applications
at the same time.

RECOMMENDATION:
 Install a fix pack containing this APAR.

When starting an application, the Axis2ServiceConfigPlugin
list will be initialized. If many applications are starting
simultaneously, the list will be modified by all these
applications simultaneously because the list is not thread
safe. That can cause some elements in this list to be missing.

PROBLEM CONCLUSION:                                             
Fixed the problem by modifying the Axis2ServiceConfigPlugin     
list to be thread safe to avoid the NullPointerException.       
                                                                
The fix for this APAR is currently targeted for inclusion in    
fix packs 7.0.0.33, 8.0.0.9 and 8.5.5.3.  Please refer to the   
Recommended Updates page for delivery information:
