Description of change

resolves uPortal-Project/uPortal-start#468

[jgribonvald]

For me the change seems good, but someone tested it ? I didn't what on where are used these features (which portlets ?)

[ChristianMurphy]

I ran a smoke test clicking through the admin views.
But as noted in the parent issue:

if you could take it for a test drive and ensure it works in your environment/preferred JDK, it would be appreciated. 🙇

It is used for a few chart jsp views in core https://github.com/Jasig/uPortal/search?q=visualization&unscoped_q=visualization
