I think we should use .equals() here, otherwise it looks like a
recommendation that the intent is for those classes to never implement it...

I don't know of any design intent, so yes, I meant more as a practical

Unless they subclass then using equals() which I thought unlikely it
makes no difference here.
But it would be proof against that to use equals, unlikely to matter as
it might be ..

Hi Jay,
You were going to remove hashCode/equals from CCM, but instead you
simply removed it from the patch. You still need to edit it to remove
the existing methods.
Oh yeah ! CCM is gone from the latest webrev. I expect that was not
intentional.
Also, I'm not sure == is a good way to compare ColorSpace instances -
Phil?
Neither ColorSpace nor ICC_ColorSpace over-ride equals or hashCode and
all the predefined ones are constructed as singletons so it seems
unlikely
to cause problems
Should it use .equals() on principle, though? Otherwise we are baking
in the assumption that it doesn't implement equals() into our
implementation of the CM.equals() method. Might it some day implement
equals (perhaps it isn't a practical issue today, but it might be in
the future when we forget that it was omitted in this usage we create
today).
I guess what I'm asking is if it is a design feature that different
objects are considered non-equal (such as an object that, for
instance, has only predetermined instances that are shared by
reference and reused). I think color spaces are sort of in-between in
that we define a few constants that simply get used by reference in
99% of cases, but that isn't a design feature, more like a practical
issue...
