[Bug classpath/22861] [Swing] plaf uninstall should not try to remove UI items

[gcc-bugzilla at gcc dot gnu dot org]

I get a nullpointerexception in my class that extends JTable and implements
setFont() to do something with that font since the uninstall from the plaf does
a setFont(null).

Exception during event dispatch:
java.lang.NullPointerException

All items that have UIResource equivalents (FontUIResource etc) should not be
set to 'null', but to sane defaults.
Or, in other words, the UI should have defaults (and know what to do with
'null' values), not the widget.

I have checked in a fix for that. Could you please retest?

Works for me now. I'm closing this bug.
