我在WildFly 10，Hibernate 5.2.2和一个简单的JAX-RS / JPA应用程序上使用这样的实体：
@Entity
@Cacheable
public class MyEntity implements Serializable {
@EmbeddedId
private MyEmbeddableId id;
// other fields, hashCode, equals, getters and setters
}
@Embeddable
public class MyEmbeddableId implements Serializable {
private String foo;
private String bar;
// hashCode, equals, getters and setters
}
所有工作都像预期的那样，但如果我重新加载应用程序（不重新启动WildFly），那么在实体加载中我得到：

如果我重新启动WildFly，它会再次运行。此外，如果我禁用缓存，部署重新加载后也可以正常工作。
我做错了吗？这是Hibernate或WildFly中的错误吗？
