Hi Justin,
had a very quick look, it seems like a gray image  and no colormap was
supplied for it?
A bug nevertheless, would be nice if you could open a ticket with enough
data to reproduce the issue.

We are progressively abandoning support for native JAI btw (as we cannot do
anything about some of its bugs), that might be part of the problem.

Cheers
Andrea
