ActiveMQ SecurityException：用戶名[defaultUser]或密碼無效

我將servicemix從4.4.2升級到5.5.0。似乎有一些安全配置我錯過了。 servicemix中的ActiveMQ版本現在是5.12。我在日誌文件中看到以下異常。ActiveMQ SecurityException：用戶名[defaultUser]或密碼無效

日誌中顯示的IP是我的WebsphereServer。 activeMQ控制檯將其顯示爲我的隊列的使用者。
我可以找出正在使用的[defaultUser]是什麼？我在activemq.xml中啓用了匿名用戶訪問。部分activemq.xml粘貼在下面。

<plugins> 
    <simpleAuthenticationPlugin anonymousAccessAllowed="true"> 
    <users> 
      <authenticationUser username="smx" password="pwd" groups="users,admins"/> 
      <authenticationUser username="karaf" password="pwd" groups="users,admins"/> 
      <authenticationUser username="system" password="pwd" groups="users,admins"/> 
      <authenticationUser username="user" password="pwd" groups="users,admins"/> 
      <authenticationUser username="defaultUser" password="pwd" groups="users,admins"/> 
    </users> 
    </simpleAuthenticationPlugin> 

    <authorizationPlugin>

      <authorizationEntry topic=">" write="users,admins,anonymous" read="users,admins,anonymous" admin="users,admins,anonymous" /> 
      <authorizationEntry topic="ActiveMQ.Advisory.>" read="users,admins,anonymous" write="users,admins,anonymous" admin="users,admins,anonymous"/> 
     </authorizationEntries> 
     </authorizationMap> 
    </map> 
    </authorizationPlugin> 
    </plugins>
