Nimbus JTree renderer properties persist across L&F changes

FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
The following UI properties, documented at http://docs.oracle.com/javase/7/docs/api/javax/swing/tree/DefaultTreeCellRenderer.html, are supposed to be instances of UIResource if they are defined by the L&F:

1. "Tree.leafIcon"
2. "Tree.closedIcon"
3. "Tree.openIcon"
4. "Tree.selectionForeground"
5. "Tree.textForeground"
6. "Tree.selectionBackground"
7. "Tree.textBackground"
8. "Tree.selectionBorderColor"

On the Nimbus L&F, all are defined, but none of them implement UIResource. This causes them to incorrectly persist across L&F changes.
