This patch (committed) adds some checks for the constructors in the 
ColorModel class:

2006-06-09  David Gilbert  <david.gilbert@object-refinery.com>

    * gnu/testlet/java/awt/image/ColorModel/MyColorModel.java: New file,
    * gnu/testlet/java/awt/image/ColorModel/constructors.java: New file.

I didn't fix the failures in Classpath yet, because I'm still unfamiliar 
with the dependencies in this part of the code.

Regards,

Dave
