Applet Application throwing ClassFormatError

[gaurav]

I have successfully configured Shibboleth IDP (On Machine 1) and Shibboleth
SP with Apache (On Machine 2). Deployed some sample application on Tomcat 
(On Machine 2) built using JSP and everything was working fine with
Shibboleth setup.

After this I have deployed our Application which uses Applets on Tomcat (On
Machine 2), configured it behind Shibboleth and I started getting strange
ClassFormatError on browser. 

Tried accessing from multiple browsers/different machines/ cleared temp
files from Java Control Panel but I was still getting the error. 

Was surprised with error, removed the application entry from
"apache24.config" file in SP and accessed the application and it works fine. 



Again, I have created again a sample "Hello World" Applet application
configured it behind SP, but I am still getting the same exception.
