Hello,

Does anyone know whats wrong with worldMngr and what can i do?

You'll need to speak to the MCP team, we haven't supported MCP since start of this year, and 1.2.5 since end 2012. Why are you using such an old version, anyway?

I get the error message on the forge/install batch so i think its a forge problem

 

I have to use the old version because Minecraft 1.2.5 isnt upwards compatible.

 

( Btw. the same problem: http://www.minecraftforge.net/forum/index.php?topic=934.0 )

Same error with older JDK7 and an other minecraft_server.jar (1.2.5)

No way in hell are we supporting 1.2.5, let alone DEVELOPING for 1.2.5.

You are on your own if you wish to work on such old systems, and judging by the fact that you cant solve a simple issue like this, I don't think you should be doing what you are doing.
