org.springframework.boot.actuate.endpoint.EndpointId cannot be cast to java.lang.String 异常处理

用了spring-boot-starter-actuator 之后出现异常: java.lang.ClassCastException: org.springframework.boot.actuate.endpoint.EndpointId cannot be cast to java.lang.String.
详细的异常如下：

很奇怪的异常，看EndpointId的代码也重写了toString()方法，更奇怪的是找不到MvcEndpointUtil的代码出处。困扰了好几天，关键是百度了好久也没到有用的信息，也在群里问了一下，没有人回复。今天用google搜了一下，本来也不太抱希望。最后无意中发现了一篇文章(异常处理)[http://www.codeleading.com/article/8276162799/]，发现跟我碰到同一个问题，最后解决方法不显眼，但还是被我发现了。

更新 IDEA Jreble 插件

果断试了一下不用jrebel来启动，果然可以了。不晓得jrebel在这个过程中做了什么操作。
