I am running a minecraft server with forge on Windows 7. When I start the server with the "nogui" option, I only get following output, then it "freezes":
However, the server runs normally and responds to all commands, just the text output is completely lost. I tried running the server with and without mods, used builds 200, 202 and 217 and nothing worked. (Just to be sure I also tried unmodified minecraft_server.jar, that one works fine)
Without the "nogui" option, it behaves very simillary, except the server window appears and contains all the lost output.
