I'm marking it as major because this makes any debugger unusable when
using swing components in jython.

The tracing facilities are not working when an event is being received
from swing.

The attached file shows this: on jython 2.2.1, when entering text in the
text area created, it correctly enters the trace_dispatch method,
whereas in jython 2.5 it doesn't (when it should).

Bug still present in 2.5.2, two years later.

I would expect this tracing to work. Time to finally investigate for 2.7.

AWT listeners have specific, historical support that go outside the normal calling convention for Jython. That's why one can add a callback on older Jython without the more recent support for single method interfaces.

We should merge this in to use the normal code path (but later than 2.7.1)

Having said that, I still would expect some interception to be possible, so this is still open.
