problem with creating instances of an ArrayListMultimap

[GoogleCodeExporter]

Hello,

I use this interface in order to keep a short names: 

public interface MyMultimap<T> extends ListMultimap<T,MyClass<T>>{}

the problem is that when I try to create objects declared with my interface it 
seems that it's not possible:

MyMultimap<T> mmm = ArrayListMultimap.create();//don't works

but, with the initial interface obviously it works:

ListMultimap<T, MyClass<T>> lengt1seq = ArrayListMultimap.create();

It's a little weird, can someone give me a hint? 

Thanks,
Adrian B.

ArrayListMultimap implements ListMultimap and does not implement MyMultimap. If 
you want to be able to do something like this, you'll need to do something like 
create an implementation of MyMultimap that extends ForwardingListMultimap and 
then create it using an ArrayListMultimap as the delegate (or make MyMultimap a 
class that extends ForwardingListMultimap itself).

Questions like this should be asked on StackOverflow 
(http://stackoverflow.com/questions/ask) rather than here.
