Nick Boldt commented on JBIDE-17535:
------------------------------------

{quote}how can you get Early Access connectors visible whereas Early Access checkbox is not checked?{quote}

Yes, that's sort of the point. They remain visible and a NPE is thrown instead.

As to steps to reproduce, see the Steps to Reproduce in this JIRA.
