Alessio found some threading issues with his console, and with those fixed I am able to use it within protege and it no longer hangs after one or two commands. (Thanks!)
Using the latest abcl, there also seems to be some bundle: url goodness happening. I no longer see the unbound variable issue, and I see bundle: uris for abcl-defined lisp code being loaded - snap attached - I recorded a screen movie and grabbed the last it showed before crashing.
I then go and try to load some other code and the whole thing crashes. I'm including the relevant portion of the console log. The last complaint is:
4/15/10 6:24:59 PM [0x0-0x15e15e].Protege41[3978] Unable to autoload JAVA:JCLASS-FIELDS
Not sure why other bundle: code would load but not this.
