-------------------------------------------------------------

For any method name apart from {{call}} and {{doCall}}, dynamic Groovy will call the delegate. There is special logic for those names. Static Groovy has had different behavior for those methods.

>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 3.0.2, 3.0.3, 3.0.4, 3.0.5

>            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}
>
