odd exceptions coming from pdb

I frequently see this error pop up when I'm debugging Jython code with pdb : 

UnboundLocalError: "local variable 'exc_traceback' referenced before assignment"

I typically see it when I need to step into function call and then Jython will throw the above error back at me. 
Is this a known bug in Jython?  I can't seem to find any reference to it on the Jython bug tracker or in Google.

That sounds like an unknown bug, do you have code that reliably
reproduces the problem?  To make sure we don't lose track of the bug
would you mind posting it to http://bugs.jython.org?

Any dates for Jython 2.5?

Hi,

Does anyone knows how good is 2.5b0? If I am to install Jython on a new
dev machine, should I go with 2.5b0 or 2.2.1?

Thanks,
Jack

Re: Any dates for Jython 2.5?

The very first time I used 2.5b0, I hit a bug. My code was as follows:

def mult(vals):
    return reduce(lambda x,y: x*y, vals)

This works in Jython 2.2.1, but gives this error message in 2.5b0:
   SyntaxError: line 0:-1 required (...)+ loop did not match anything at
input '<EOF>' (<stdin>, line 0)

Jython 2.5 is still beta, but this suggests that it's not ready for
production use yet.

You can always install both Jython 2.2.1 and 2.5b0, but at some point you
will need to decide whether your application code is going to be restricted
to 2.2.1 language capabilities, or whether you are targeting 2.5.0. That
probably depends on when your application needs to ship.

Hi Jack,

It is easier for me to answer your subject question "Any dates for Jython 2.5?"

Because of a few really important last minute feature additions
(mainly Java integration related -- including jythonc), there will be
at least two more betas before we get to release candidates.  The next
beta should appear in the next week or two, and will hopefully be very
close to feature-complete.  My current estimate puts the appearance of
release candidates at around February.  Hope that helps.

Re: Any dates for Jython 2.5?

Thanks Matthew for mentioning the issue in another reply. I'll
go with 2.2.1 for now.

Thanks Frank, for the update! Any chance that the issue reported
by Matthew is a known issue? Looking forward to the 2.5 release!
