class Ball implements Comparable {

    public int compareTo(Object o) {
    	return 0;
    }
    
    public static void main(String[] args) {
    	LinkedList<Ball> foo = new LinkedList<Ball>();
    	Collections.sort(foo);
    }
}

javac gives:
   [javac] Lint.java:15: warning: [unchecked] unchecked method invocation:
<T>sort(java.util.List<T>) in java.util.Collections is applied to
(java.util.LinkedList<p.Ball>)
    [javac] Collections.sort(foo);
    [javac] ^
    [javac] 1 warning

eclipse accepts this code with no warning, which seems wrong because of the raw
extends clause - if you change the clause to 'extends Comparable<Ball>' and
update the compareTo method, javac likes it.
