Incorrect logic for additional resource name check

[Towdium]

In document of method additionalResourcesLocator it says:

Rules:
The Strings in the set must not end with ".class". Conflicts with other ITransformationServices will result in an immediate crash.

But inside TransformationServiceDecorator, it checks the name with this logic:

final Set<String> badResourceNames = resNames.stream().
                    filter(s -> !s.endsWith(".class") || resourceNames.contains(s)).
                    collect(Collectors.toSet());

It seems inverted to me. Am I getting something wrong?

Yes, I believe you are.

No he is right, this check is the wrong way around, this crashes if a resource does not end with .class
