This is a bit strange, here is the sample:

class Attr(object):
    def __init__(self, name):
        self.name = name

    def __set__(self, instance, value):
        instance.__dict__[self.name] = value


class Test(object):
    attr = Attr('attr')

    def test(self):
        self.attr = 5

t = Test()
print t.attr
t.test()
print t.attr

In python, if you have a newstyle object called x, and in some point define the attribute __dict__["x"] as 5 then getting the value of x. So in python that program would return:

<__main__.Attr object at 0x7f1b820b7f90>
5

On jython it returns:

<__main__.Attr object at 0x1>
<__main__.Attr object at 0x1>

A workaround would be to add a __get__ method something like this:

    def __get__(self, instance, owner):
        return instance.__dict__[self.name]

But for compatibility it would be nice to change this.

Thanks!
