The testULRClassloading and testURLClassLoader work with the proper classpath for the no copy case. When adding tests for ?useNoCopyJarHandler=true, its failing with java.lang.IllegalArgumentException: URI has a query component. I did not realize a file uri cannot have a query component. I don't understand why. I guess that will have to be handled by FileSystemContext. I'm still using the vfs version linked to trunk, so I'm not sure if you fixed this Ales.
