Thanks. When I do that, there is no reference to org.objectweb.asm, nor is there even any reference to any asm library. The information is about 800 lines long and it clearly shows classes loading from my "minimal core Drools" plugin; when I add the entire Drools distribution to the classpath I get a similar dump with loading from the complete Drools distribution. I am attaching a text file with this information but I am guessing it will get stripped away by the server. I very much appreciate your help with this.
