RussianThere was a bug back in 1.6u19, then it was solved and now it seems to be reintroduced in 1.7u25.
The solution is to add following line to the manifest: Trusted-Library: true
ClassNotFoundException from applet on Java 1.7u25 when certificate revocation check is enabled; working fine on 1.6

Question
I'm using html & jnlp to deploy the applet. The applet is signed by externally generated certificate because it needs all-permissions. It works fine on Java 1.6. On Java 1.7 it throws ClassNotFoundException being unable to find applet's main class.
The code has been compiled using 1.6 and I need it working on both 1.6 and 1.7.

var parameters = {jnlp_href: 'WebUI.jnlp'} ;
