Description
I started to use a gem of a feature called ContextInjector (https://resteasy.github.io/2018/07/19/asynchronous-injection-in-resteasy/) but immediately noticed that inheritance is a bit tricky since type variables are not deeply resolved in extractTypeVariables
Here's a patch (sorry for not having a test case, nor a pull request) that got me going. I also refer to my findings of RESTEASY-1295 since they are related to ParameterizedType handling but were not included back in the days to fix.
