EVALUATION

Font.equals doesn't take into account that the composite font may be different
in this case so the font metrics cache on SunGraphics2D may return a metrics
object from an inappropiate font.

This bug is 1.4.2_X only. It is not present in 1.5 or later.

SUGGESTED FIX

There's a very simple fix for this. Make Font.equals additionally
compare the Java "long"s which hold the pointer addresses for the "peers".
They'll be different for each of these cases.
