+1. That's what the collection APIs do, innit?
 
Not really:

    Set set = new HashSet ();

    assertTrue( !set.contains(null) );
    set.add( null );
    assertTrue( set.contains(null) );
    
    Map map = new HashMap ();
    assertTrue( !map.containsKey(null) );
    assertTrue( map.get(null) == null );
    
    map.put( null, null );
    assertTrue( map.containsKey(null) );
    assertTrue( map.get(null) == null );

get() will still give you null, but containsKey will return true.
rephrase: its what they should be doing! IMNSHO :D. "null" as a key does 
not make sense.

cheers!
