question on some swing docs

[Steve Sides]

While adding @param and @return to various swing files, I came across 
this. The javadoc descriptions for 
javax.swing.plaf.TreeUI.getPathBounds() and 
javax.swing.plaf.basic.BasicTreeUI.getPathBounds()  have stated it 
returns null "if any component in path is currently valid".  Is that right?

The getPathBounds() in BasicTreeUI returns null if tree or treeState is 
null.  Should it be l "if any component in path is currently *invalid*"?
Since I essentially parrot this in the @return tag statement for 
TreeUI.getPathBound() , I'd rather make sure it 's correct in the first 
revision.

thanks for any help,
