Aled Sage created BROOKLYN-569:
----------------------------------
Summary: Aggregator enricher lost on rebind (due to
ClassCastException)
Key: BROOKLYN-569
URL: https://issues.apache.org/jira/browse/BROOKLYN-569
Project: Brooklyn
Issue Type: Bug
Reporter: Aled Sage
I had an aggregator for {{systemload.average}} on the cluster. On rebind, it
failed with the {{ClassCastException}} shown below. The consequence (I think?)
is that the enricher is not added to the entity.
