HstSiteConfigurer: сбой инициализации ComponentManager

Я работаю над One Hippo CMS, когда я запускаю сервер Tomcat, я получаю эту ошибку

5.02.2019 18:23:45 ERROR main [DefaultHstSiteConfigurer.initializeComponentManager:264] HstSiteConfigurer: ComponentManager initialization failed. org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.hippoecm.hst.content.beans.manager.ObjectConverter' defined in class path resource [org/hippoecm/hst/site/container/SpringComponentManager-content-beans.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Annotated class 'org.example.myproject.beans.Urldemo' for primarytype 'myproject:urldemo' is a duplicate of already registered class 'org.example.myproject.beans.Simple'. You might have configured a bean that does not have a annotation for the jcrType and inherits the jcrType from the bean it extends, resulting in 2 beans with the same jcrType. Correct your beans. at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1745) ~[spring-beans-5.1.1.RELEASE.jar:5.1.1.RELEASE]
