Did you ever get this resolved? I have a similar error with 1.4.2_08
I set the option as the following, and things seems to be right
But I don't know why
JAVA_OPTS="-server -Xms2000m -Xmx2000m -XX:MaxPermSize=128M -XX:MaxPermSize=128M -XX:NewSize=512m -XX:MaxNewSize=512m -Xss400k -Djava.awt.headless=true "
