FULL PRODUCT VERSION :
JVM 1.6

ADDITIONAL OS VERSION INFORMATION :
Windows XP

A DESCRIPTION OF THE PROBLEM :
We have a problem with applet caching here. This is a problem with JVM 1.6 only. In JVM 1.4.2 the applet is working fine.

In JVM 1.6 When caching is enabled the applet is showing “class not found” exception at run time.

But the caching is disabled the applet is working fine. Anybody can confirm this is a bug with JVM or any changes are required in the applet code?

More and more users are moving to JVM 1.6 and the problem is reported by many. Removing Cache_version parameter from applet tag also solves the problem. But this is causing performance impact in application

Any suggestions?
