Dániel Dékány resolved FREEMARKER-133.
--------------------------------------
Fix Version/s: 2.3.31
Resolution: Fixed
This is fixed in Git (2.3 and 2.3-gae branches).
Turns out, the code just didn't put together the list of accessible methods
well, and has put in some inaccessible ones too sometimes. I'm very surprising
that this bug could survive so long.
The Collection return type you mention, that in itself is not a bug or
something, that's just a synthetic method, because the superclass declared it
as Collection, and then the generic type is narrowed down to List.

> Consider the following code:

> where orders is com.google.common.collect.ArrayListMultimap. An
> IllegalAccessException is thrown, because
> com.google.common.collect.AbstractListMultimap where the get method is
> defined is package-private.
