Known issues
------------
* Resolving a class registered by supertype or interface will only autowire the members inherited from its supertypes and in the case of interfaces none at all. To work around this issue, use a qualifier. Alternatively you could immediately resolve all registrations once by qualifiers after registering everything. See "[Registering and resolving using qualifiers](#Registering and resolving using qualifiers)".
None! Found one? Let us know on github.
