ERROR DESCRIPTION:                                              
ArrayIndexOutOfRangeException in WsMap in Proxy or ODR.         
This can cause request failures through the Proxy or ODR.       
The WsMap.contains or WsMap.remove methods may both             
erroneously throw this exception.                               

LOCAL FIX:                                                      

PROBLEM SUMMARY

USERS AFFECTED:
All user of IBM WebSphere Application Server

version 6.1 who are also using the Proxy or
users of IBM WebSphere Extended Deployment
using the On Demand Router.

PROBLEM DESCRIPTION:
An ArrayIndexOutOfBoundsException can
occur during Proxy or On Demand Router
startup when assigning indices to
property names.

RECOMMENDATION:
None

An ArrayIndexOutOfBoundsException may occur when the Proxy or
On Demand Router starts as a Proxy filter calls
WsMapFactory to assign an index to a property name.

PROBLEM CONCLUSION:                                             
The ArrayIndexOutOfBoundsException was fixed by enlarging       
the array for property values appropriately.                    
The fix will be included in service pack 6.1.0.9 for            
WebSphere Application Server Network Deployment.
