So TreeNode.equals(LayerNode) presumably is OK, but LayerNode.equals(TreeNode)
will throw a ClassCastException.  This made me wonder if our implementation of
TreePath.isDescendant() has the equals() test around the opposite way to the
reference implementation.  So I wrote a Mauve test to check this implementation
detail...but (unfortunately) it shows that this isn't the problem (the checks
pass on both GNU Classpath and Sun's JRE 1.5.0_06).  Anyway, I'll commit the
test to Mauve now in case anyone wants to look at it - the file is:

gnu/testlet/javax/swing/tree/TreePath/PR27651.java
