Cached, local-class-supporting task names (#1409)

Fixes issue #1177 

`MapMaker#weakKeys()` makes the `Map` use identity comparison for the keys, while also enabling the automatical removal of dropped classes from the cache.

The changes are the same as in #1399, except now the original patch is modified instead of a new one being created.
