At some point, that constants were renamed in the ICC spec, and as a result, the new constants with the different names were added to ICC_Profile. The old one were not removed to avoid breaking compatibility. It wasn't considered critical, since both constants have the same value.

I just included all constants supported by the JDK for completeness.
