Following code leads to the crash:
- result can be seen after the code section
<code>
from javax.swing import JFrame
from javax.swing import JMenuBar
class Framework(JFrame):
def __init__(self):
JFrame.__init__(self)
self.menuBar = JMenuBar()
self.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)
self.setLocation(50, 50)
self.setSize(400, 400)
self.setTitle("A title...")
self.setJMenuBar(self.menuBar)
self.setVisible(True)
if __name__ == "__main__":
framework = Framework()
</code>
<result>

JFrame inherits from class java.awt.Frame a pair of setter and getter called setMenuBar and getMenuBar respectively. These methods return or take java.awt.Menubar.
So, when you call
self.menuBar = JMenuBar()
jython resolved it to a call of setMenuBar and hence a conversion exception.
Rename menuBar to something else will avoid the exception

The same did not happen in Java so I have had no idea.
Thanks.

Is this issue resolved to the OP's satisfaction?
If so, I will close it.
Thanks to Anthony for the solution.
