I closed and ran it a second time. The spawn area was successfully prepared. Not sure if this is a problem or not. Just a heads up.

 

Just to clarify, it was a one-time problem?

 

Your run.bat will always use x86 Java, btw. You only have an x86 system, so that run.bat is overkill.

Change it to this (you will have better results):

Code:

java -Xincgc -Xmx512M -jar craftbukkit-0.0.1.jar
