Ben,
Yes, I didn't think JDT was completely set up to work standalone so
you'll need to run headless if you need to use the capability. Perhaps
when we switch from using JDOM to using AST
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=124372), we'll find that
AST will work standalone. We've not experimented with that yet.
