I see.
Following try showed me that instances aren't affected by
modification in class definition.
but this helped
x.test = a().test OR x.test = y.test
The only thing left is how to initiate modification, it's a
swing application and i think interp.exec don't stop until
it's done. Maybe somehow call it from jython itself - but need
to pass PythonInterpreter instance.
Thanks.
class a:
def test(self):
print 'first'
x= a()
class a:
def test(self):
print 'second'
y= a()
x.test()
y.test()
