Why doesn't this compile?

Wtf.java

public class Wtf {
    public static abstract class Foo<V> { // Removing this type parameter allows it to compile
        public <T> T bad(Class<T> fooClass) {
            return null;
        }
    }

    public static class Bar {
    }

    public static class Baz extends Foo {
        public <T> T good(Class<T> fooClass) {
            return null;
        }

        public void go() {
            Bar badBar = bad(Bar.class); // This won't compile
            Bar goodBar = good(Bar.class); // But this will
        }
    }
}
