Issues with migrating from Jersey 1.x to 2.x

I am currently migrating from Jersey 1.x to 2.x.
The latest issue I stumbled upon is the linking part.
In 1.x we have a custom filter that produces the links.
In 2.x the replacement seems to be the _DeclarativeLinkingFeature_.

However, in Jersey 2.x all descriptors (Entity, Field, Ref) are not visible.
Is there a way to customize this? So far the only way I can think of is to implement some horrible monstrosity with reflection.
