----------------------------------------

Dear Les:
        I have encountered this problem when tried to serialize the Subject object in my application.I am developing an distributed application,and the Subject will generate at the Provider end,then I restore it in redis and in Consumer end find it use sessionId.
but when debugging I get an Exception says DelegatingSubject cannot be serialized...I have tried to decrease the version of Shiro to 1.0.0-incubating,whose Subject had implemented the Java.io.Serizlizable interface so that can be serialized.But I find its contents seems not complete  in redis server,can you give me some advices,I will very appreciate it !Lookkkkkking forward to your reply!

> I assume that DelegatingSubject is meant to be serialized since it does implement serializable. I noticed that the class inner class StoppingAwareProxiedSession is the culprit. Would the issue be resolved by simply making the Session interface, ProxiedSession class, and StoppingAwareProxiedSession serializable?
