Sorry for the confusion it was a bug in my simple test-program where I
requested the colormap both times from the same pixmap, it actually
turned out the it only works when creating a 16-bit pixmap.

This is the code I used for testing:
  printf("\nDepth: %d", gdk_rgb_get_visual()->depth);
  GdkPixmap* pix = gdk_pixmap_new (NULL, 10, 10, 16);
  void* cm = gdk_drawable_get_colormap ((GdkDrawable *)pix);
  printf("\nIt returned with 16-bit depth: %d", cm);
  fflush(stdout);

  GdkPixmap* pix2 = gdk_pixmap_new (NULL, 10, 10, gdk_rgb_get_visual()->depth);
  void* cm2 = gdk_drawable_get_colormap ((GdkDrawable *)pix2);
  printf("\nIt returned with gdk_rgb_get_visual()->depth: %d\n", cm2);
  fflush(stdout);

And it prints the following output running on my Nokia770:
Depth: 24
It returned with 16-bit depth: <Some valid integer>
It returned with gdk_rgb_get_visual()->depth: 0

On my Xorg-6.8.2 system powered by a nvidia card runnig in 24-bit mode
its different of course:
Depth: 24
It returned with 16-bit depth: 0
It returned with gdk_rgb_get_visual()->depth: <Some valid integer>

So could this be a bug in the GTK version used on the 770 or is
classpath just using GTK in a way which is not always guaranteed to
work?

Sorry for nerving that much and thank you in advance, lg Clemens
