I took a quick look at the DefaultInternalFrameDriver, and all these
operations are implemented with the same (faulty) assumption outlined in
issue199. These can, however, be implemented by calling the methods of the
underlying JInternalFrame directly.
Are there still any interest in these?
Abstractly, yes (we wrote a workaround for this issue that it would be nice
to retire), although the system we were testing when I submitted this bug
has been binned now so there is no great urgency from our side.
