1.7.2 Crash when creating world/No connection to servers (Build: 10.12.0.1034

[Split00]

For several days now I have been researching both online and on your forums to figure out the specific problem I am having with no luck. I don't have any mods installed just a version of forge that I wanted to test before adding the mods that need it. When installing and actually running the game it seems to be fine. When at the home screen I click multiplayer to see the blue bars just continuously go back and forth and when joining I have no connection. When trying to create or load a world I crash resulting in the crash log below.

I'd hazard a guess here. It looks kind of like your java runtime has a security issue and is not allowing connections on the loopback (127.0.0.1) interface. I don't know what to tell you at this point.

[fabricator77]

It's failing to create the child process, which is the actual server that generates the world, saves it etc.

Could be a security setting, in java or your anti virus.

 

Try using a locally installed MinecraftServer, adding forge to it and see if that works.

I found that it was the newest version of Java that is having a problem with minecraft. I tried installing an older version and the error was gone.
