Major Description
Currently, test_tools.sh will fail if the JAVA_HOME environment variable is not set, even if there is a java on the PATH. I generally trust Philip on testing, but I've been bitten a few times by this requirement while trying to build a release. It's low priority, but if it doesn't violate anyone's test-related sensibilities, I'd love to have this test just run with the first "java" it finds on the path if JAVA_HOME is not set.
