I found the awnser, So imma post it here in case someone with a simmilar question finds this post.
The moment Flash connects to a local socket server it will send the following:
<policy-file-request/>
We will have to answer with a policy file AND IMMEDIATLY CLOSE THE CONNECTION.
Do you see that sentence written in ALLCAPS there?
That's the thing none of the tutorials you will find say, but it's crucial.
Flash will close the connection the instant it get it's policy file, and reconnect.
Posted below is extremely bad written java code, that will do the trick.
I found this thing @ http://www.actionscript.org/forums/showthread.php3?t=156451
