This occurs because the default SessionRegistry implementation uses an in-memory map to store UserDetails. In order to resolve this, you must ensure that you have properly implemented the hashCode and equals methods.

The second problem occurs when restarting the application container while the user sessions are persisted to a disk. When the container has started back up, the users who were already logged in with a valid session are logged in.
