Hi Doug,

On further evaluating it (among other possible HashMap replacements), I'm not convinced that they are enough better to commit.

That's a shame. What about that idea of having a factory method that would take a Class object and return an appropriate Map implementation based on that? I think this would be used more than IdentityHashMap as users could be instructed to use that factory method all the time (unless they had a good reason not to) instead of having to exercise judgement (like they have to do with IdentityHashMap). One could even add a detector to findBugs (like it has for Integer.valueOf and similar).

Best, Ismael
