Server GUI Text box is empty (.exe only)

When starting the minecraft-server.jar of 13w39a the GUI Text box stays empty. The console works as normal.
You can join the server and play on it.
If you start the .jar without a batch, it loads a new world that seems to be saved nowhere.
Commands via GUI still work, but 'help' doesn't print into the GUI (but in the console)
Example in the attached pictures.

Workaround for windows users:
Start the JAR version of the server instead of the EXE version, then you get the console output.
Start the server by a command file start_server.cmd for example like this:

java.exe -Xmx2G -Xms2G -jar minecraft_server.1.7.10.jar --nogui
