[bug-classpath] [Bug swing/23252] New: JTree.setModel(null) causes chain of NullPointerExceptions

[WBaer at gmx dot de]

Hi,

If JTree.setModel(null) a NPE happens, I fixed this, afterwards
in BasicTreeUI.getPreferedSize() a NPE happend, I fixed this, 
afterwards BasicTreeUI.paint() throws NPE - there I have not
the knowledge to fix it anymore.

I attach the diffs for JTree.setModel() and BasicTreeUI.getPreferedSize().

You can observe it with the Beanshell Console. Just start the console
right-click in the background and choose new Class Browser. You have to
ignore the other failures during startup up to this point :-)
