I am using JTrees, plural, and they all have a common data model. When
the user creates a new tree, the model changes and the changes appear in
all trees currently on screen. I want to cancel this behvior so that
other trees on screen are not changed when the model changes under them.

Since JComponent has the addPropertyChangeListener method, I assume that
it is executed somewhere in the constructor execution for a new JTree.
It follows that if I then execute the removePropertyChangeListener
method, I should achieve my objective.

Here's the problem:
removePropertyChangeListener(PropertyChangeListener pcl) needs the
PropertyChangeListener that was sent to
addPropertyChangeListener(PropertyChangeListener pcl) originally.

The question is, how do I get pcl?
