Signature of method 'x.actionPerformed()' does not match signature of the base method in class 'AbstractAction' same with 'ComponentAdapter'

[yogi1967]

For some reason the stubs created by JythonHelper causes loads of this errors for me? If I zap the stubs, the error goes away.

from javax.swing import AbstractAction
class X(AbstractAction):
    def actionPerformed(self, event):
        pass

same with java.awt.event.ComponentAdapter
