----------------------------------------------------------------
Well, I tried another build of OpenJDK 11, OpenJDK 13 and cleaned up
dependencies, but no changes. It has appeared randomly before, but restarting
helped. The only recent change was switching to Groovy 3, but I cannot see how
that would affect Freemarker.
I ended up writing a wrapper for ListMultimap.

The only recent change was switching to Groovy 3 – maybe the wrong return type
of the method is a compiler bug.
