Altassian support have resolved the blocker, we're back in business!

We are again impacted by recurring Atlassian Marketplace scalability problems and cannot release new versions. Atlassian has been informed. Our usual workaround will be to host new versions on Bitbucket ( https://bitbucket.org/javahollic/jemh-releases/src/master/ ) customers *must* verify compatibility before downloading and installing updates!
