> 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}
