There is already an issue on this: 
http://www.netbeans.org/issues/show_bug.cgi?id=33920
It's just a warning, it does not break anything, but I know that it's 
annoying when it's printed even when there is no misuse.

This can be considered as a defect IMO. It should not end up with an 
exception, I would expect that it will use empty global options. Feel 
free to file a defect on javacvs.
