      But the class is present in the new version of Mondrian too, see attached screenshot with decompiled jar structure.

      One workaround I found was to add dependency into olap translator's module.xml pointing at the org.mondrian module, which contains the mondrian jar.
      But this action is not required when using Mondrian 3.5.0.
