Mattias (and Esteban)... Well.....you guys gave me the solution to the problem, but in a wildly indirect way. I downloaded the source for zip4j, added a bunch of logging so I could figure out where the code was hanging, went to replace the existing library and.....hmmm, where the heck IS the existing library?
Long story short, was not including the zip4j.jar in the app classpath. Added the debug version, and, surprise, surprise, it worked. So, it turns out I should have been getting a ClassNotFound exception from the classloader. Not sure why drools would just stop and NOT throw a ClassNotFound exception, but that is no longer my concern. Thanks to everyone who participated in leading me to a solution...a typical false-positive error. And to Davide....you were right, not a Drools problem at all. It was the nut behind the keyboard (aka PEBKAC).
