The IncompatibleClassChangeError may stem from having the very same class in the very same version, but loaded by two different class loaders, or by the same class loader, but from two different JARs. If you put two copies of a JAR inside two different directories and create an instance of a class whose definition come from one of the JAR and then try to use that instance in another part of your code where the definition of the class, albeit identical, came from a different JAR, Java consider the two classes different and spit that exception. This is how I remember it...
