创建名为springApplicationAdminRegistrar的bean时出错

Question

在将project从Spring Boot版本从1.2.3.release迁移到1.3.0.release之后，我已经开始得到以下异常。

创建类路径资源[org/springframework/boot/autoconfigure/admin/springapplicationadminjmxautoconfiguration.class]中定义的名为'Spring ApplicationAdminRegistrar'的bean时出错：调用init方法失败；嵌套异常是javax.management.instancealreadyexistsexception:org.springframework.boot:type=admin,name=springapplication

有任何指针来调试这个问题吗？

Context是从代码中手动加载（Java代码）以获取bean，删除该代码解决了这个问题。然而，我的问题解决了，但仍然不确定它是如何与上一个版本的spring Boot一起工作的。
