    Hi Andrus,

    Sorry I'm still not done.

    I've been searching and hacking for way to long now to try to get
    this code in. The basic problem is that like you I could not find a
    way to wrap the original implementation of the method using the CGLib
    implementation path that exists in the rest of the code. It appears
    to be easy with the Enhancer API.

    I prefer your approach to the Enhancer but I'm at a loss as to how to
    make it work. I'll try to get some more time tomorrow to look at it
    but I'm going to be very busy doing J1 stuff.

    Does anyone know if the CGLib folks are on IRC anywhere?

    TTFN,

    -bd-
