How does this work if there are multiple restrictions on the same element (e.g.
like MultipleRestrictionsRestrictedClass in the test)? Seems like we're only
adding one item to the annotations list.

This works with MultipleRestrictionsRestrictedClass because that's one
annotation with an array value containing multiple Restrictions. It doesn't work
with repeatable annotations (which are new in Java 8 afaict). Reimplemented in a
way that does.
