Passing Subclass Type to Java Generic Method with reflection throws no Exception

So I was experiencing a weird bug in Spring where an abstract controller method was being called and being passed an object that the type system should not have allowed.

This is a simple example that demonstrates the bug.

import org.junit.Test;

import java.lang.reflect.InvocationTargetException;

public class RandomJavaTesting
{
    public static class Animal {
    }

    public static class Cat extends Animal {
    }

    public static class AnimalManager<T extends Animal> {

        // This gets called and doesn't blow up
        public void add(T animal){
            // This will throw a class cast exception
            // Why does this blow up here for CatManager?
            this.callAdd(animal);
        }

        public void callAdd(T animal){

        }
    }

    public static class CatManager extends AnimalManager<Cat> {

        @Override
        public void callAdd(Cat animal)
        {
            // This will never run
        }
    }


    @Test
    public void callingGenericMethodWithSubClassType() throws InvocationTargetException, IllegalAccessException
    {

        CatManager manager = new CatManager();
        Animal animal = new Animal();
        AnimalManager.class.getDeclaredMethod("add", Animal.class).invoke(manager, animal);

    }
}

This test gives the following exception:

Basically, my question is, why does calling the add method not cause a ClassCastException. Why does calling callAdd cause the exception? I understand that generic information isn't preserved at runtime however I was under the assumption that extending a class caused the type parameters of a generic class to be preserved. This is the mechanisim behind the Guava TypeToken. Or, at least that's what I thought.
