WorkerComparator not following spec when multiple interface inheritance

org.glassfish.jersey.message.internal.MessageBodyFactory.WorkerComparator#getTypeDistance has a bug when the wanted type is two or more deep interface inheritance.

Exemple:

I have 2 interfaces, D and C. C extends D and a class A implementing C. If we model horizontally interface inheritance and vertically class inheritance we would get something like this.

A - C - D

Object

If I have two MessageBodyWriter one for Object and one for D, when selecting which is closest, getTypeDistance will return 2 for Object and 3 for D which is not valid. It makes no sense to have an interface or class be further from another than Object. Object should always be the furthest class from any given class.
