Sometimes people create so-called fat JARs. That is, the build a JAR which not only contains their code, but also the code of each and every library that they are using. I have hit that problem in the past when I was using a JAR from a tool which included a full copy of the Stanford Parser. It meant, when I added a more recent version of the Stanford Parser to my project, unpredictable things would happen. Cheers, -- Richard
