The circuit breaker parent rejects the requests because of a fielddata overflow (9KB + 866MB). The limit is tied to the JVM HEAP size.

TODO:
- review the code: there may be more field uselessly set as fielddata
- tune ES or Maven or Surefire ? MAVEN_OPTS Xmx
- activate ES for the two previews; that's not related to the unit tests issue but worth to also improve
see https://github.com/nuxeo/nuxeo-helm-chart/blob/master/nuxeo/values.yaml#L122 , current chart is 1.0.14 - consider not using the embedded ES, even for the unit tests
=> for the functional tests, wait for related Platform improvements on their next chart - lower requested resources
