> Key: BROOKLYN-482
> URL: https://issues.apache.org/jira/browse/BROOKLYN-482
> Project: Brooklyn
> Issue Type: Bug
> Reporter: Aled Sage
> Priority: Minor
> Fix For: 0.12.0
>
>
> In version 0.11.0-rc2...
> As described in https://github.com/apache/brooklyn-docs/pull/172, it's
> important that config key default values are immutable.
> However, in a yaml catalog item or blueprint if you declare a config key of
> type {{java.util.List}} (or Set, Collection or Map) with {{[]}} then that is
> mutable.
> For example:
> {noformat}
> brooklyn.catalog:
> itemType: entity
> items:
> - id: entity-with-keys
> item:
> type: server
> brooklyn.parameters:
> - name: my.list.key
> type: java.util.List
> default: ["myDefaultVal"]
> {noformat}
