Invalid Java Error

Hi there.
I'm not sure whether this is a Java bug, LilyPad error, or my fault (probably) but I have gotten this error twice in the terminal so far:

Code (text):

# A fatal error has been detected by the Java Runtime Environment:

./start.sh: line 1:  2225 Aborted                java -server -Xms256M -Xmx256M -jar hub.jar

It should be self explanatory I guess. In the meantime, I will be switching my start.sh file to an infinite loop to restart after crashes like these, because I can always execute commands afterwards.
