Thank You for your comments.
We have been working with Oracle Support team and their explanation is that JRockit has some issues with axis code and it crashes in apache axis code whenever a soap request is submitted to a webservice on weblogic. The reason for the crash is that there are two versions of javax.xml.soap.SOAPPart, and the wrong one is loaded ahead of the right one. If you would like to follow up you can refer to CR264864.
Good luck.

Hi Satya,

We are facing the same problem of JVM crashing with Illegal Memory Access. We are running on BEA 8.1 SP4 with jrockit-R27.6.0-jre1.4.2_17. We do use Apache Axis version 1.3 2244 client to invoke a webservice.
Your help is greatly appreciated.

Thank you
