NimrodGolan commented 1 month ago

The context After upgrading to v3.1.0.RELEASE we are are getting the following error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grpcHealthService' defined in class path resource [net/devh/boot/grpc/server/autoconfigure/GrpcHealthServiceAutoConfiguration.class]: Could not generate CGLIB subclass of class io.grpc.protobuf.services.HealthServiceImpl: Common causes of this problem include using a final class or a non-visible class

What do you wish to achieve? To be able to start our application properly
