ClassLoader::loadClass should have type (String, boolean)Class AND (String):Class (it is overloaded) and then be resolved to (String,boolean)Class But some debug output in transformArgs reveals: uncurry, args.length = 2, params.length = 1, methtype:(java.lang.String)java.lang.Class This means the typechecker has picked the wrong alternative for some reason.
