@zakkak I had to add this for our Quarkus jobs because in the (quite old) version we are using there were substitutions with return type mismatches. The offending substitution seems to be gone on master, but I have not checked all the others. Maybe things are fine, maybe not. Just a heads up. :)

Hi @zapster, thanks for the heads up.
It looks like there are some failures on Quarkus main as well which I am working on in quarkusio/quarkus#35847 and quarkusio/quarkus#35956

The return types of substitution methods must match the return type of the target method. Incompatible types can lead to failures in the compiled code, e.g., unexpected
NullPointerException, which are hard to debug. Note that none of the changed substitutions suffered from these problems because although there were mismatches, the specified types were usually a super type of the target return types (e.g.Objectinstead of the concrete type). Still, this verification helps catching problems in new substitutions early.
