Problem with WebRememberMeManager
---------------------------------
Key: SHIRO-141
URL: https://issues.apache.org/jira/browse/SHIRO-141
Project: Shiro
Issue Type: Bug
Components: Authentication (log-in)
Environment: Windows vista running Eclipse Galileo v.3.5 w/ Google App
Engine plugin - Debug mode
Reporter: Chris Dutrow
I executed the following code to see if I needed to get the current user again
after logging out:
Subject currentUser;
currentUser = SecurityUtils.getSubject(); // < --No exception
currentUser = SecurityUtils.getSubject(); // < --No exception
currentUser.logout(); // < --No exception
currentUser = SecurityUtils.getSubject(); // < --EXCEPTION
Resulting in the application throwing a NullPointerException from
WebRememberMeManager.
Here is the stack trace: (I'm currently trying to learn how to install and use
JUnit)
32046 [btpool0-1] WARN org.apache.shiro.mgt.DefaultSecurityManager - Delegate
