It seems ridiculous that java.util.Date (and anything using it) has to depend
on java.awt.ComponentOrientation just to get a constant for a Locale field.

Surely this is inside-out, and "pollutes" an otherwise reasonably "vertical"
package model. (Although I would prefer the Date 'numerics' to be separated
from the 'display/locale specific' side.)

The Locale should define some "text-direction" type properties, and then the
AWT package should use those at the appropriate times.

This makes much more sense!
