A DESCRIPTION OF THE PROBLEM :
Super does not seem able to accept a named parameter type... method bar4() below does not compile.

public class Foo<T> {
        // These are all OK
        void bar1(Class<? extends T> x) {}
        <X extends T> void bar2(Class<X> x) {}
        void bar3(Class<? super T> x) {}

        // but this one causes javac to complain... why?
        <X super T> void bar4(Class<X> x) {}

        public static void main(String[] args) {
                Foo<Number> f = new Foo<Number>();
                f.bar1(Integer.class);
                f.bar2(Double.class);
                f.bar3(Object.class);
        }
}

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Try to compile code snippet above, see error.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
expected it to compile, and for <X super T> to work similarly to <X extends T>
ACTUAL -
won't compile


ERROR MESSAGES/STACK TRACES THAT OCCUR :
Foo.java:8: > expected
        <X super T> void bar4(Class<X> x) {}
           ^
Foo.java:12: illegal start of type
                f.bar1(Integer.class);
                               ^

etc.

REPRODUCIBILITY :
This bug can be reproduced always.
