Which Java is working best? Ubuntu

Which linux is running best right now on Ubuntu server 12.04? I have install oracle 6 and it does great. The problem with it is the media browser doesnt work. I installed 7u9 and the lag is awful, audio breaks up on me. Is there any one that works good for this?

Why MB doesn't work? It should work with 6.

The problem is with Oracle 6 is the Media browser always has a 404 java error when you look at it with browser.

if you post some detailed logs with the error we might help. It should work.

I checked the detailed logs and its working with java 6. here is what it shows me with the browser.

is there an error in serviio.log?

Nope, It shows to be processing everything. This happened before to me, I had to upgrade to java 7 for media browser to work.
