A few DirectColorModel related bugs were fixed
recently by Nicolas Le Sommer, you might want to try
the current sources from CVS, and see if that works
better for you.

If it doesn't, then you should split the 82nd line
DirectColorModel.java into several lines, and see
which expression exactly raises the exception.

best regards,
