Cookie NPE in logs

[William E.]

It seems in cas 5.2, and 5.1.6, I'm seeing several instances of Cookie related NPE's in the logs.  Presumably from tomcat/cas restarts and browser refreshes where users were logged in before the cas/tomcat restart.  Not sure where to report issues like this so the CAS developers become aware so they can potentially do something more elegant with the scenario.

A year later and I'm seeing these NPEs on CAS 5.3.6 as well.  If anyone has done anything elegant to make these go away please share. ;)
