Updater executer fails with InvalidItemStateException

A Groovy update script that traverses /content/documents fails immediately on the first hippo:translation node it encounters.

Steps to reproduce:
1. start GoGreen
2. navigate to the "Script and Run Updaters" panel in the Dev perspective
3. enter the following Groovy script:

package org.hippoecm.frontend.plugins.cms.dev.updater

import org.onehippo.repository.update.BaseUpdater
import javax.jcr.Node

public class UpdaterTemplate extends BaseUpdater {

public boolean update(Node node)

{ log.info(node.getPath()); }

public boolean revert(Node node)

{ throw new UnsupportedOperationException("Updater doesn't implement revert method") }

}

4. select 'Path' and enter the path '/content/documents'
5. click 'Dry Run'

Expected result: the script logs the path of all nodes under /content/documents
Actual result: the script quits after the first hippo:translation node with an InvalidItemStateException:
