Subject Re: On Scala 2.12.7

I don't think so. Spark brings the Scala dependency, and I don't think
the installed scalac matters in this respect.
Darcy there was an open question about whether this enables you to
back out the workaround you created for 2.12.6. I tried removing it
and it failed again, so left it in as still needed.

are very close to a release, and Scala 2.12 build of Spark 2.4 is beta anyway.
