(using RC3) In the following example code, I get the warning "Unnecessary cast
from Set<Integer> to Collection". But if I remove the cast, I get the (expected)
error "Type mismatch: cannot convert from Set<Integer> to Collection<Number>"...
so, I don't think the cast is unnecessary.

package test;

import java.util.*;

public class Foo {
    
    @SuppressWarnings("unchecked")
    public static void main(String[] args) {
        Set<Integer> set = new HashSet<Integer>();
        set.add(42);
        Collection<Number> collection;
        collection = (Collection) set;
        System.out.println(collection.iterator().next());
    }

}
