Objectify -类注册期间的StackOverflowError

Question

我有一个配置了Objectify 5.1.13的Java App Engine Maven项目

<dependency>
    <groupId>com.googlecode.objectify</groupId>
    <artifactId>objectify</artifactId>
    <version>5.1.13</version>
</dependency>

使用相关的过滤器

<filter>
    <filter-name>ObjectifyFilter</filter-name>
    <filter-class>com.googlecode.objectify.ObjectifyFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>ObjectifyFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

在注册类的过程中(由ServletContextListener在开发服务器启动期间执行)，我得到了一个堆栈溢出错误

ObjectifyService.factory().register(classToRegister);

下面是dev-server启动过程中显示的错误

抱歉，我不得不缩短堆栈跟踪，所以不接受超过30k字符的文本
