We are running JDEdwards OneWorld pacakage using DB2 UDB, WebSphere 3.5.4, AIX 4.3.3 all running on RS6000 boxes. Some of the Client machines are using a browser, others are using a 'fat' client. Every now and again, the browser users get the message

"java.lang.ArrayIndexOutOfBounds n>=n"

What would cause this kind of message????
