    [ https://issues.jboss.org/browse/GTNPORTAL-2917?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779556#comment-12779556 ] 

Lucas Ponce commented on GTNPORTAL-2917:
----------------------------------------

I've uploaded an example based on a similar issue reported by an user in forums:

https://community.jboss.org/message/821502#821502

To reproduce the error:

1.- Build jsf2-rf4-test project and deploy in gatein.
2.- Create a test page with the jsf2Rf4TestPortlet included in jsf2-rf4-test project.
3.- Access to test page with logged user, activate polling function in the portlet (this will create periodically ajax calls to the server).
4.- Shutdown gatein.
5.- Re-start gatein without close the browser (to maintain ajax calls).
6.- you will be able to reproduce NPE exceptions and gatein will be blocked in

Hope this example helps to debug the issue.
