Have you tried overloading the relevant classes in your project?
I remember I did that once with Color.class to turn the constants into
properties so they were writable. (That class is not relevant for this
matter though. Also it is no longer relevant/required since Color was
enhanced a long while back.)
In this case, maybe adding a method is all that is required?
