8 years ago Krakatau requires access to the referenced classes so it can determine sub/super classes and which classes are interfaces. java/lang/IllegalMonitorStateException is a core class in the Java language, so it should be in your rt.jar. If Krakatau doesn't find it automatically, you'll need to pass its location via the -path argument.
