A DESCRIPTION OF THE PROBLEM :
In the API under javax.swing.tree.TreePath there is a code example whose last assignment gives an error at compile time: "incompatible types" as getUserObject() returns an Object.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
   DefaultMutableTreeNode selectedNode =
       (DefaultMutableTreeNode)selectedPath.getLastPathComponent();
   Object myObject= selectedNode.getUserObject();

ACTUAL -
   DefaultMutableTreeNode selectedNode =
       ((DefaultMutableTreeNode)selectedPath.getLastPathComponent()).
       getUserObject();
