[jira] [Commented] (SHIRO-323) DelegatingSubject class cannot be
serialized.
[ https://issues.apache.org/jira/browse/SHIRO-323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13176694#comment-13176694 ]
Les Hazlewood commented on SHIRO-323:
-------------------------------------
Hi Michael,
I'm not sure if the DelegatingSubject should be serializable: the implementation always needs a SecurityManager to function, and a SecurityManager instance is not serializable. If a DelegatingSubject instance was passed across the wire, something would need to acquire the local SecurityManager, associate it with the de-serialized DelegatingSubject, and then bind it to the thread for duration of the invocation.
Did you get this working in your JMS environment? If so, how? Did you use the Subject.Builder to recreate the Subject on the receiving side?
Thanks,
Les

> 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?
