[cp-patches] 2 Patches for getPreferredScrollableViewportSize

[Anthony Balkissoon]

The ViewportLayout patch I committed yesterday was causing some
NullPointerExceptions because some classes that implemented Scrollable
hadn't properly implemented the getPreferredScrollableViewportSize
method.  These two patches implement this method in JTree and JList.
There are no more null pointer exceptions relating to this although many
of the classes that extend JTextComponent are simply returning
getPreferredSize inside this method when perhaps they should be
returning something else.

The two patches are attached.
