Frequently Asked Questions

1. Class cannot access its superinterface ?

If you encounter an Exception like the following:

Exception in thread "main" java.lang.RuntimeException: by java.lang.IllegalAccessError: class org.javassist.tmp.java.lang.Object_$$_jvst41b_0 cannot access its superinterface MyClass

This means that the interface MyClass isn't accessible, it must be public.

2. How to check if my model is sound ?

Pamela offer high level model definitions but it does so by tricking the Java compiler using abstract constructions. The compiler cannot detect which methods are unimplemented and are subject to raise an unbound exception NotImplementedError.

You can easily check if your model is sound with a simple test:

ModelFactory factory = new ModelFactory(MyRootModelClass.class);
factory.checkMethodImplementations();
