今天遇到一个非常奇怪的spring容器问题，先看日志

]-303 Loading XML bean definitions from class path resource [com/eucita/component/activemq/applicationContext-activemq-topic.xml]
-75 Using JAXP provider [org.apache.xerces.jaxp.DocumentBuilderFactoryImpl]
r]-103 Trying to resolve XML entity with public id [null] and system id [http://www.springframework.org/schema/beans/spring-beans-2.5.xsd]

r]-103 Trying to resolve XML entity with public id [null] and system id [http://activemq.apache.org/schema/core/activemq-core-5.0.0.xsd]

环境是

tomcat6.0（中间换glassfish2.0也试过）

spring2.5

activemq5.0

使用eclipse，和IDEA调试程序

问题是：在出了上面的日志以后，CPU占用率从50%左右直接下降到2-3%，然后就一直停在这里，没有响应。

 

team里面有3台同时出现这个问题，调试了一段时间找不到原因，试着重启了电脑，然后问题消失。

猜想是IDE造成的，但是同时几个人，不同IDE，出同样问题，非常诡异。
