[jira] [Created] (BROOKLYN-545) Rebind failure after using cluster
with `enableAvailabilityZones`
Aled Sage created BROOKLYN-545:
----------------------------------
Summary: Rebind failure after using cluster with `enableAvailabilityZones`
Key: BROOKLYN-545
URL: https://issues.apache.org/jira/browse/BROOKLYN-545
Project: Brooklyn
Issue Type: Bug
Affects Versions: 0.12.0
Reporter: Aled Sage
Assignee: Aled Sage
Priority: Critical
I was running Brooklyn 1.0.0-snapshot. On restarting Brooklyn, it failed to rebind with the {{NullPointerException}} below in the log.
This probably affects lots of older versions of Brooklyn as well (I've guessed at 0.12.0 in the "affects" field!).
Problem is that our xstream deserialization is trying to insert a null key into a {{ConcurrentHashMap}}. This is because the {{DynamicCluster}}'s config key {{dynamiccluster.zone.failureDetector}} has a mutable default value!
The {{ProportionalZoneFailureDetector.zoneHistories}} contains {{locationProxy}} instances for locations that no longer exist.
I'm guessing the consequence of this bug is that if anyone uses {{enableAvailabilityZones}} in an app and then terminates the app (thus unmanaging the locations), any subsequent use of an app with {{DynamicCluster}} will cause rebind to fail.
