Shiro authentication issue after a wrong login

[dhbello]

There is an bug when shiro authentication is setup, and an user try to login with invalid credentials. To reproduce, follow this steps:

• Try to login with invalid credentials, the incorrect messages will appear.
• Then, try to login with valid credentials, a blank page will appear.

It looks like the eu.europa.ec.re3gistry2.web.controller.ValidateSalt, blocks the request - if the "/login" url pattern is removed in the ValidateSalt filter mapping, works correctly.

I believe that this issue is related of how the eu.europa.ec.re3gistry2.web.controller.Login servelet redirects a failed login or related with shiro configuration. Any ideas?
