1) Add more than one PropertyChangeListener to any
subclass of JComponent that uses
SwingPropertyChangeSupport (using
addPropertyChangeListener())

2) In the propertyChange() method of the class that
implements PropertyChangeListener, remove a
a listener from the JComponent (using
removePropertyChangeListener())

==> Concurrent modification problem -- if a listener
is removed whilst the listeners are being sent messages,
then some listeners will be skipped: the implementation
of SwingPropertyChangeSupport does not synchronize its
vector of listeners (according to the comment, this is
because Swing is single-threaded). Concurrent modification
can occur even in a single-threaded environment!

This bug is a show-stopper for our application!
(and I can find no workaround)
