Run attached java application on grayscale video board (i.e. Barco or Dome) on 
Win32 with Non-Linear Static Gray palette set, with the latest ladybird:
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

The application displays a grayscale gradient. Note that some of the shades
are mising from the gradient (use attached native windows application
curpal.exe to see that: start dragging mouse from curpal to any pixel at the
screen to see it's color).

The missing colors are the one from first 10 and last 10 palette entries.
Here is an email from Jerry on this issue:
------------
When 8-bit grayscale support was first added for Win32 in 1.2, there
were only two possibilities supported:

     a) the colormap is 256 gray entries in monotonic increasing
        order.  This was called GS_STATICGRAY.

     b) the middle 236 entries were forced to be gray (if the
        FORCEGRAY environment variable was set).  This was   
        called GS_INDEXGRAY.

Now that we're adding support for grayscale colormaps in non-monotonic
order without the FORCEGRAY environment variable being set, we need   
to distinguish more than one case of grayscale indexed color maps.    

For the case, when we don't inherit a grayscale color map, but want to
create one because the FORCEGRAY environment variable is set, we still
need to zero the first 10 and last 10 entries.  This tells the code   
in IndexColorModel.java to ignore those ten entries for rendering     
purposes and since all the other entries are opaque gray, an inverse  
gray LUT will be computed, which is used in some native rendering code.
(There is no way through the IndexColorModel constructors to say that  
certain entries should be ignored.  We adopted a convention internally 
that transparent black entries would be ignored.)

For the non-monotonic case, as long as all 256 entries are opaque gray
colors, then IndexColorModel.java should do the right thing.

The fix in "suggested fix" implements this suggestion.
The customer has verified that it fixed the problem.

This has been fixed in Merlin as well.
