ActiveMQ 启动异常

   在按照 《ActiveMQ in Action》的操作步骤进行操作的时候，ActiveMQ异常终止后，总是不能启动，总是在报错误。

经过搜索了之后，悲催的发现这个是ActiveMQ5.4.1的一个bug。在5.5里面给解决了。

its a known bug and fixed in current trunk (5.5-SNAPSHOT).

https://issues.apache.org/jira/browse/AMQ-2935

    但是为了避免在学习的过程中，因为版本不匹配等原因产生问题，于是继续搜索，终于找到了解决办法。主要是由于 5.4.1 这个版本引入延迟发送的功能引起的， 解决办法是在<broker>中添加 schedulerSupport="false" 属性，禁掉scheduler功能。

参照文章http://blog.csdn.net/technofantasy/article/details/6037295

代码

<broker xmlns="http://activemq.apache.org/schema/core " brokerName="SIBBusModule-TestDeCharge-td0sib01s" useJmx="true" persistent="false" useShutdownHook="false" schedulerSupport="false" >

还有就是删除activemq目录下的data/xxxx/scheduler 下的所有内容，不过这种我没有尝试
