Have a look at Jakarta Commons Collections, it has MultiKey and
MultiKeyMap, which works exactly as you describe.
If you want a generic version, let me know.

The Jakarta team has been very reluctant in starting a generic version.
Finally, there has been some advancement there. However, I have made
my own generic version, if you send me an e-mail, I can send it to you.
Mention which classes you would like.
Alternatively, there is ‘larvalabs’.
