How to repeat:
Hard to repeat in all cases, some installations on OSX seem to be affected whilst others do not. It may be an issue with users using fink, also.
Suggested fix:
Setting libawt to headless seems to resolve the issue, please set the following within the catalina.sh script for JAVA_OPTS:
JAVA_OPTS='-Xmx512m -Djava.awt.headless=true'
