Hi Linus, this has been reported as issue 4929 (http://argouml.tigris.org/issues/show_bug.cgi?id=4929). My local patch is to allow ProjectBrowser.getInstance() to call ProjectBrowser.makeInstance(). I didn't attached it to the issue because it was said that it violates the logic of makeInstance(). The solution is to make ProjectBrowser a TRUE singleton, but I guess this can only be done when there is a solution for enabling modules to add items to the GUI (see issue 4925, http://argouml.tigris.org/issues/show_bug.cgi?id=4925), without requiring the init of GUI during Module subsystem init.

Hello again!
It looks to me like the ProjectBrowser now requires makeInstance(...) to be
called before getInstance().
There are two solutions to this. Either fix the ProjectBrowser or make the test
cases call makeInstance() first. At first glance I prefer the last one which
will probably remove the possibility to create ProjectBrowser using the
constructor without arguments and replace it with some more test code to do
initialization. Is this the right way to go?

I suspect that this is a consequence of the reordering of the
initialization sequence.
I'll do some testing to see if my theory is correct.
