Another Linux Kernel 3 issue?

Hi all,

I've just upgraded to Ubuntu 11.10 and am having a couple of problems.

Trying to download the example programs gives me occasional java errors, and sometimes when running the 'webserver' example (when I can get it downloaded) I get garbage returned in the web-page.

An example of the java error can be seen at:-

Hope that comes out right..

My pc is dual-boot linux and windows XP. when I swap over to xp all is fine.
Anyone using 11.10 successfully?
