It seems like you code against a specific sub-type and not the parent class Symfony\Component\Config\Definition\Builder\NodeDefinition as the method performNoDeepMerging() does only exist in the following sub-classes of Symfony\Component\Config\Definition\Builder\NodeDefinition: Symfony\Component\Config\Definition\Builder\ArrayNodeDefinition. Maybe you want to instanceof check for one of these explicitly?
