David,
I reported a similar problem to Sun (see earlier post on ColorModel
exception). Their response is given below.

It looks like the IllegalArgumentException comes from a BufferedImage
constructor:
public BufferedImage (ColorModel cm,
WritableRaster raster,
boolean isRasterPremultiplied,
Hashtable properties)
This constructor calls cm.isCompatibleRaster(raster), which must be
returning false. The code in
DirectColorModel.isCompatibleRaster(Raster)
looks OK to me, so possibly the Linux port has somehow constructed
an IntegerInterleavedRaster or a DirectColorModel with inconsistent
arguments when running on your framebuffer. We've certainly run
SwingSet
on 32 bpp cards and haven't seen this. Without more detail on the
IntegerInterleavedRaster and DirectColorModel than is printed out in
the error message, I can't tell for sure why isCompatibleRaster() is
failing.
