The docs are wrong. It should read self.super__foo() (with two
underscores).

from javax import swing

class MyComponent(swing.JLabel):
    def __init__(self):
        self.setText("Hello from jython")
    def paintComponent(self, g):
        print "paintComponent"
        self.super__paintComponent(g)

import pawt
pawt.test(MyComponent())
