That is a good question. The potentially different keySet values should be freely substitutable or else there seams to be something wrong. If they are FS, then the VM should be able to pick any. But it is a big assumption to say that *all* maps that extend AM behave in such a way.  We could go back to the previous version and shadow the field. That seems safest.

Note: there is work in progress to remove these fields.
