1. Create a vanilla DXP 7.1.x
2. Apply in portal-ext.properties (more config detail in comments):

   portal.jaas.enable=true

1. Start the portal
2. Login as admin

Expected results: the progressBar appear when loading

Actual results: The progressBar does not appear and an error is thrown -> i is not defined

Reproduced with dxp-5-7110
Reproduced with dxp-11-7110
Reproduced on 7.1.x

I was not able to reproduce the issue on master, because the progressBar is not used on logging.
