When calling

{portletSession.invalidate()}

the user is logged out.

This is due to over aggressive handling of the session invalidation in equinox.http.servlet.

The fix is pending the next release upstream here: https://git.eclipse.org/r/#/c/123084/

Steps to reproduce:
1) login to the portal
2) deploy the attached war
3) add all the portlets under "undefined" to a page
4) click one of the buttons on the page

 expected results:
the page should re-render with the test case passing

 actual results:
you are logged out of the portal and get redirected to the login page
