Clientless VPN and Java not working correctly

In a recent discovery we found that the newest version of java will not work with our Cisco SSLVPN setup

We are using an ASA5510 with 8.0.4 IOS version and 6.1.3 ADSM version and most users use an mstsc.exe smart tunnel to rdp into our terminal server farm.

Our laptops are being imaged with Java 6 update 3 (this works fine) then upgraded to Java 6 update 11, after which the smart tunnel appears to launch but a connection cannot be established. Reinstalling the older version of Java resolves the problem.

I was wondering if anyone else has encountered a similar problem and found a workaround. Currently, company equipment is not being upgraded to the latest version of Java but personal equipment is a different story.
