@gsmet it looks like this addition is enough to handle #49413
I explored the option of removing the !method.parameterType(0).name().equals(DotName.createSimple(Object.class.getName())) check above to make it detect the generic handleRequest method in the abstract class and register it but no matter what I tried I keep getting:
