Admin UI reports permission error if the request it made results in ANY exception

A lot of the pages in the UI report permission errors even when the actual problem is some other exception.  For this screenshot, I clicked first on the Overview, and then on Ping ... there was a misconfig in the ping handler where it was not declaring a default field, so the query generated an exception which is attached to the issue.  I did not have a security.json file.

I also saw this on other things besides Ping when I was clicking around the admin UI during a solr service restart.  The version info showing where the git repo was when I compiled from branch_9x:
