Why are identical jars getting loaded from two differnet places? what in your config is loading jars from your .m2 cache?!?!?! Having two versions of the same class show up in your classpath is exactly the sort of thing that will cause a ClassCastException. Two classes with the same name and the same byte code loaded by two different class loaders are not the same class as far as the JVM is concerned, and any subsequent attempts to use one in place of the other will throw ClassCastException... http://onjava.com/pub/a/onjava/2003/11/12/classloader.html (skip down to "Class Definition" if impatient) : > lucene-test-framework-4.0.0.jar only from .m2 ...that jar is the reason why you are seeing attempts to load the MockFixedIntBlockPostingsFormat at all. I re-iterate my earlier question: what in your setup is attempting to load jars from your .m2 cache -- because that really makes no sense to me at all. : > > > > It's odd that it talks about a Mock class as I'd normally associate : > > that : > > > > with unit tests; presumably that's part of the Service Loader : > > mechanism. -Hoss
