Are you by any chance running an older version of gcj as your java version?  
There is a known bug in some of these where they don't correctly configure the 
headless environment, even if the correct parameters are passed.  This causes 
exactly the kind of errors you're seeing.

If this is the case you'll need to install a more recent JRE (or update your 
path to point to one which is already present).
