Until Spring Framework 5.1.15, a FactoryBean with a non-default constructor defined via component scanning would cause an error. This behavior has changed as of https://github.com/spring-projects/spring-framework/issues/22409. Regardless of this change we want to ensure that we avoid triggering eager initialisation. `SimpleFactoryBean` has been written this way so that the tests fail if early initialization is triggered regardless of the Spring Framework version. Fixes gh-15898
