Greetings dev, The root cause of CONTINUUM-2712<https://jira.codehaus.org/browse/CONTINUUM-2712>, is not clear at the moment, but when responding to it I couldn't help but wonder if we might want to update the installation instructions on the web site to suggest using Java 6 or later.
If it turns out to be caused by a dependency continuum uses that is built with Java 6 or later, I am even more inclined to remove references to using Java 5. It is at end-of-life and will only become more common moving forward. Brent
