Here you could update to current 10.14.4 -- it was my version for
testing. There is some (low) chance that the problem was due to Apple
and is already solved.

For the moment you can just return to an older scala component in
$ISABELLE_HOME_USER/etc/settings, e.g. like this:

  init_component "$HOME/.isabelle/contrib/scala-2.12.6"

or to whatever other version you see fit.

End-users won't have to build Isabelle/Scala anyway: a release provides
finished Isabelle/Scala/jEdit jars.
