Updating the Multijob-plugin to version 1.22 broke our Jenkins instance.

probably caused by https://github.com/jenkinsci/tikal-multijob-plugin/pull/75
I searched the entire internet but could not find any EzTemplateBuilder class... and there is no version 1.0.5 in https://github.com/jenkinsci/ez-templates-plugin

This exception happened when accessing a Hierarchy view:
