      Description

        This code:

        interface Task<E extends Exception> {}
        class Comparator<T> {}
        class CustomException extends Exception {}

        class TaskQueue<E extends Exception, T extends Task<E>> {}

        abstract class Test {
            abstract <E extends Exception, T extends Task<E>> TaskQueue<E, T> create(Comparator<? super T> comparator);

            void f(Comparator<Task<CustomException>> comp) {
                TaskQueue<CustomException, Task<CustomException>> queue = create(comp);
            }
        }

        compiles in 6 and 7 but fails to compile in 8.
