Inheriting from a Java class with no default constructor

How can I inherit from a Java class that doesn't have a default 
constructor? If I try this:

from java.beans import PropertyChangeSupport

class A(PropertyChangeSupport):
     def __init__(self):
         PropertyChangeSupport.__init__(self, self)

A()

I get: TypeError: Default constructor failed for Java superclass 
java.beans.PropertyChangeSupport

Is this impossible, or am I doing something wrong? Or is there a bug in 
Jython?
This was tested on SVN trunk.
