Creating this issue as we spoke about the possibility to use Jandex a few times, so we have a one place for discussions.

Pro:

• Fast meta-data retrieval when using pre-existing index

Con:

• Additional dependency
• Not so good documented

Implementation-wise it would make sense to implement this in form of another MetaDataProvider.

We could also make meta data providers more pluggable, so we don't have a strict dependeny to this. The Jandex provider would then be plugged in under AS while in other scenarios the normal annotation-based provider would be used.
