I am exposing EJB as a webservice. When I'm deploying the EJB as a webservice using WSAD, the server when starting dumps core with the following exception.

JVMDG217: Dump Handler is Processing a Signal - Please Wait.
JVMDG303: JVM Requesting Java core file
JVMDG304: Java core file written to C:\Program Files\IBM\WebSphere Studio\Application Developer\v5.1.2\javacore.20060427.161130.2920.txt
JVMDG215: Dump Handler has Processed Exception Signal 11.

On exploring the Core Dump files I have seen some parsing errors in the Symbol Table class which I had no clue of.
There's an interesting twist here though. When I reduce the number of variables in my EJB classes to a certain number, the service is deployed and the server gets started properly. But when I increase the variables by 1, after a certain limit th server dumps core and fails to start. I have no clue why its happening.
I tried putting WSAD fix pack 9 but even then I had the same problem. I need toadd some new variables but am unable to do it due to this error. Could anyone pls help?
