Hi all.
I just got a full IS built on top of the Vaadin/Spring/JPA stack. Then I ran .jsp pages via Spring security to catch clients logging in and out. I also found that the session timeout was set aggressively to 7 minutes for security reasons, so users found themselves getting kicked out and having to log in again after the set time.
When we used Vaadin 6.4.8, everything seemed ok. But after the system-wide upgrade to Vaadin 6.6.2, a weird error came out when session is timed out. Check this out:
Apart from the regular session timeout window (normal, red-sized), we received this one, where loginform.jsp somehow didn’t respond.
Note that this happens only in Firefox browser, other are working as expected. Any idea about the root of this error? Help needed urgently. Thanks in advance.
EDIT: It actually behaves similarly on Internet Explorer (i.e. the error also comes out).

You must have a backup of this so that if it went wrong you can roll back to the previous version. So if you don't have the backup proceed below
