I think we can consider this more of the same in SPARK-25398, and attach it 
to that JIRA. If we end up passing the current 2.4 RC I'll untangle it.

Can you create a jira ticket and put more description? This is a bug fix 
and strictly speaking it's nothing about scala 2.12. It's just the scala 2.12.7 
compiler helps you to find this bug.

branch-2.2 is fine, but branch-2.3 should be fixed.

ah so scala 2.12.7 is smarter on finding mistakes. LGTM then. Do you know 
how long this bug exists? It will decide how far we should backport it.
