Paul King commented on GROOVY-9662:
-----------------------------------
>From the log when I run tests in the grails-views/views-json subproject:
{noformat}
result.jsonText ==
'{"_links":{"self":{"href":"http://localhost:8080/player","hreflang":"en","type":"application/hal+json"}},"name":"Cantona"}'
| | |
| | false
| | 1 difference (99% similarity)

{"_links":{"self":{(,)"href":"http://localhost:8080/player","hreflang":"en","type":"application/hal+json"}},"name":"Cantona"}
...
{noformat}
Each level has a boolean property {{first}} which is checked to avoid a comma
before the first element. Here, {{first}} from an outer level (where it is
already set to false) is returned, hence the extra comma one level down.
> Groovy 3.0.5: Closure delegate is not working properly
> ------------------------------------------------------
>
> Key: GROOVY-9662
> URL: https://issues.apache.org/jira/browse/GROOVY-9662
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 3.0.2, 3.0.3, 3.0.4, 3.0.5
> Reporter: Puneet Behl
> Assignee: Eric Milles
> Priority: Major
>
> In Grails Views, we are using closures to generate JSON using
> `StreamingJsonBuilder`. The HAL implementation for an entity now generates an
> incorrect JSON after updating to Groovy 3.
>
> Here is the problem code snipped from Grails Views:
> {code:java}
> jsonDelegate.call(LINKS_ATTRIBUTE) {
> call(SELF_ATTRIBUTE) {
> call HREF_ATTRIBUTE, viewHelper.link(resource: object, method:
> HttpMethod.GET, absolute: true)
> call HREFLANG_ATTRIBUTE, locale.toString()
> call TYPE_ATTRIBUTE, contentType
> }
> Set<Link> links = getLinks(object)
> for (link in links) {
> call(link.rel) {
> call HREF_ATTRIBUTE, link.href
> call HREFLANG_ATTRIBUTE, link.hreflang?.toString() ?:
> locale.toString()
> def linkType = link.contentType
> if (linkType) {
> call TYPE_ATTRIBUTE, linkType
> }
> }
> }
> }
> {code}
>
> Although the `resolveStatergy` for the closures is `DELEGATE_FIRST` but I
> believe that is not working correctly because it works if I change the above
> to:
> {code:java}
> delegate.call (...
> {code}
>
