[Bug AWT/16734] New: CardLayout: next card not drawn after current card is removed

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

In Acunia's layout.CardLayoutRemove2 test, after the first card is
removed, the next card is not shown.  When a card is removed, the next
card should be drawn.

This doesn't seem to be fixed.  I either get:

or worse,

Yes, I'm certain that this test was working after I put in my fix. 
But obviously something else has broken it.  I'll look into it.

The problem was in Container's remove() method, where the component's
parent was being set to null too early.  This is now fixed in the
java-gui-branch.  Please verify.
