After a little research, it looks like most of the native source (including LittleCMS) was stripped from OpenJDK. I'm not sure where to go from here. Any help would be greatly appreciated.

Volker recently did some work in this area. Could you please try again with the new development snapshot:

The latest built still doesn't implement LCMS. It is implemented in OpenJDK using JNI but swapped with a dummy implementation.

I have test the follow line:
new java.awt.image.ComponentColorModel( ColorSpace.getInstance(ColorSpace.CS_GRAY), new int[]{1}, false, false, 1, 0 );

and it work without problems in the repository version. We use a GNU Classpath implementation now without sun.java2d.cmm.lcms.LCMS. All references to sun.java2d.cmm.lcms.LCMS.DummyColorTransform should be in dead code. I have checkin it for 3 weeks. You should test the latest snapshot from http://weblog.ikvm.net/.

If you can reproduce it with the latest snapshot then some Java sourse lines that reproduce the error will be very helpful.

You can reproduce the problem using a custom ColorSpace. PDFRenderer is loading its ColorSpace from a file, "sGray.icc". This results in a call to CMSManager.getModule() which returns the partially implemented LCMS. I can upload this for you and get you some source if you need it.

For now I have modified the PDFRenderer source to use ColorSpace.CS_GRAY.

Thanks for the tip with the custom ICC_Profile. I have checkin a junit test case that show the bug. Now I look for a fix.
