      toString() on a DBObject with a UUID property fails since JSON.serialize(..) cannot handle UUID. This stacktrace is the result

      java.lang.RuntimeException: json can't serialize type : class java.util.UUID
	at com.mongodb.util.JSON.serialize(JSON.java:202)
	at com.mongodb.util.JSON.serialize(JSON.java:109)
	at com.mongodb.util.JSON.serialize(JSON.java:28)
	at com.mongodb.BasicDBObject.toString(BasicDBObject.java:75)

      Fix is pretty simple. We just have to add 

              if ( o instanceof UUID ){
            UUID c = (UUID)o;
            BasicDBObject temp = new BasicDBObject();
            temp.put( "$uuid" , c.toString() );
            serialize( temp, buf );
            return;
        }

      to public static void serialize( Object o , StringBuilder buf ) in JSON and everything is fine. Please find attached fix and testcase.
