Exception in class file transformation

Hi Folks !

I am getting following error in a two-tier application (Web-client talking
to an RMI server)". When the web Servlet client is the Apache Tomcat things
work fine. However when I run it inside JDeveloper, it throws following
error. I used to work. Don't know what I changed to cause this. can you
think of something ? Thanks,

-Sanjay

I switched to JDK 1.5 and it worked !

Thank you.

Sanjay-

I've never seen that error before ... it is odd. Are you perchance  
running JDeveloper with JDK 1.6? If so, then that might be the  
problem, since we currently do not support 1.6.
