Annotation Matcher with inner Enums as Attribute Values

[MBoegers]

What's changed?

What's your motivation?

Application Frameworks like Spring often user enums for annotation attributes to restrict the possible values.
Often these enums are defined within the annotation class itself as inner enums.
Traits canot work 100% in this cases.

Anything in particular you'd like reviewers to focus on?

There is a new ToDo this line is the problem.
The root problem seems to be that the type of FieldAccess for inner enums is not set correctly.

Anyone you would like to review specifically?

Have you considered any alternatives or workarounds?
