Java SDK Version on WAS 5.0.2.X

I'm currenly debugging some WAS issues and looking to improve performance.

IBM Recommended that we stay current on the IBM JDK version for WAS.

http://www-1.ibm.com/support/docview.wss?rs=180&context=SSEQTP&uid=swg27004980#50

The shipped JDK for WAS 5.0.2.X is sr5 (cn131-20030618) however the recommended is sr8.

Has anyone tried updating the JDK? Does JDE support the updated JDK?


Thanks,

Colin
