> People have been upgrading to the Java 6 plugin and have been running
> > into an issue if they have previously cached versions of the applets.
> > I think it has to do with the way the cache is upgraded to the Java 6
> > cache from 1.5 cache.
> > To reproduce:
> >
> > 1. visit https://www.entrust.com/trustedcare/ with Java 1.5 plugin
> > (to get applet in cache). You dont need to authenticate, just
> > make sure the applet loads properly.
> > 2. upgrade your plugin to Java 6 plugin
> > 3. visit https://www.entrust.com/trustedcare/ again
> > 4. Check Java Console, exception should look like this:
> >
> > /Java Plug-in 1.6.0_01
