I am trying to upgrade a struts based Java 6 application to Websphere 8.5 from a perfectly running application in Websphere 6.1. Have made no code changes as of now. But this one throws me off.I get Verify Error / stack Underflow error as below:

At line #8 in above logs it points to the line#71 in my UrlGateway class which does nothing besides getting the parameters from the request and forwarding to index.jsp. Line #71 of my class is as below:
application.getRequestDispatcher(forwardPath).forward(request,response);//application is instance of ServletContext
Any thoughts on how to fix this? Is this due to potential bug in Websphere 8.5?
-Thanks.
