> i ran findbugs over the cobra's source code and 
> here is the bug message
> Class defines equals() and uses Object.hashCode()</b><br/><p> This class overrides <code>equals(Object)</code>, but does not  override <code>hashCode()</code>, and inherits the implementation of
>   <code>hashCode()</code> from <code>java.lang.Object</code> (which returns
>   the identity hash code, an arbitrary value assigned to the object
>   by the VM).&nbsp; Therefore, the class is very likely to violate the
>   invariant that equal objects must have equal hashcodes.
> and here is the fix
> public int hashCode() {
>       assert false : "hashCode not designed";
>       return 42; // any arbitrary constant will do 
>       }
