javadoc for getPathBounds() in TreeUI and BasicTreeUI is incorrect

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". The getPathBounds() in BasicTreeUI returns null if tree or treeState is null. It probably should read "if any component in path is currently *invalid*" (or "hidden").
