Issue1322

When try to do some simple sub-classing, get a strange metaclass error.

Just looked and threading.Timer is a factory function, not a class.
Which is why subclassing it is a no-go. Although the error message could
be a bit more clear.

I don't quite see why we can't make Timer a real class, although we get
the EXACT same message from CPython.

Not a bug?!?

You're right, Kevin, subclassing from threading._Timer works as expected.

Cpython also uses a factory function.

Which I think is counter-intuitive; it means that I can't subclass
threading.Timer: I must subclass threading._Timer, which because of the
leading underscore, is a "private" implementation detail.

Since the behaviour is the same as cpython, the jython behaviour is
acceptable, is counter-intuitive.

Since I opened the bug, I'll close it.
