Sorry about that. I fixed this.
Also, it seemed that the width was not being calculated properly, so the
labels were cut off. I fixed this too.

* javax/swing/plaf/basic/BasicTreeUI.java
(getPathForRow): Added check to prevent NPE.
(getRowCount): Likewise.
(getRowForPath): Likewise.
(getPreferredSize): Adjusted width depending on x location and
icon.
(paintRecursive): Likewise.
(getPreviousNode): Added check to prevent NPE.
(getNextVisibleNode): Likewise.
