[mhalbritter]

When running the native-image from the spring-native sample cloud-config/configserver on the sb-3.0.x branch, i get the following exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'methodValidationPostProcessor': Instantiation of supplied bean failed
