In case if anyone is having problems with the Jline, here is what your .batch should be configured as Echo off java -Xms1536M -Xmx1536M -jar craftbukkit.jar nogui -nojline pause (Please not that the memory set is differently for me then it is for you all. My server is running on 1.5GBs. Reconfigure your memory as needed.) I just figured this out today and now I don't get any information about Jline anymore! If you copy and paste what I just showed you, you should not have any more problems. I'm running Windows 7 32-bit with the last Visual C++ 2008 redistributable installed and no problems here. Hope this helps!
