Date Fri, 07 Sep 2018 08:23:00 GMT

Paul King updated GROOVY-8778:
------------------------------
    Affects Version/s: 3.0.0-alpha-3

> Constructor short-hand breaks for empty map
> -------------------------------------------
>
>                 Key: GROOVY-8778
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8778
>             Project: Groovy
>          Issue Type: Dependency upgrade
>    Affects Versions: 3.0.0-alpha-3
>            Reporter: Paul King
>            Assignee: Paul King
>            Priority: Major
>              Labels: breaking
>
> We support:
> {code}
> println Date[time:0]
> def map = [time:0]
> println Date[*:map]
> map = [:]
> println Date[*:map]
> {code}
> but not:
> {code}
> println Date[:]
> {code}
> This is a breaking change since we currently support printing an empty map without brackets
but would require them after this change:
> {code}
> println [:]
> {code}
> would need to be:
> {code}
> println([:])
> {code}
> But we require the brackets for lists (empty and non-empty) and non-empty maps already.
