Hi there,
We are a user of WebSphere 4.0.3 which operates with a JVM version of 1.3.1_12. We have recently downloaded the installer tool and the new JVM in the hope that it will bring our current JVM up to 1.3.1_16, the location that we downloaded this from is at:
http://www-1.ibm.com/support/docview.wss?rs=180&uid=swg24006479 We followed the instructions for this upgrade from the two readme txt files contained in the installer jar and the jvm jar. The actual install seemed to complete without error, but upon starting up WebSphere the following message was recorded in the /opt/WebSphere/AppServer/logs/tracefile file:

Once WebSphere has finished its startup process and all services have started too, the following error is then repeatidly outputted into the WebSphere tracefile:
java.lang.NullPointerException
at com.ibm.ws.util.CachedThread.run(ThreadPool.java:145)
However, our application that runs on this server appears to work ok even though WebSphere is reporting these errors. Are you able to help me at all? I am looking to find out what this error could be related to. Have we missed a step during installation? Is there something else we need to install or configure? The instructions do not state whether anything more is required.
I look forward to your earliest response.
Thanks and regards,
Stuart
