nginx+tomcat6+memcached异常java.lang.NoSuchFieldError: attributes

今天部署nginx+tomcat6+memcached集群

准备了如下的jar包：

tomcat修改content.xml。使用非粘性non-sticky sessions 

 <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"   
  memcachedNodes="n1:localhost:11211"  
  requestUriIgnorePattern=".*/.(png|gif|jpg|css|js)$"  
  sticky="false"
  sessionBackupAsync="false"
  sessionBackupTimeout="100" 
  transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"  
  copyCollectionsForSerialization="false"/>

启动tomcat正常，访问报错：

查询资料发现msm1.9.3之后fix了这个问题，所以进行版本升级。

重启2个tomcat，启动正常

session共享正常
