Subject [jira] [Commented] (GROOVY-9058) each parameter type not correctly inferenced
Date Fri, 05 Apr 2019 14:43:00 GMT

    [ https://issues.apache.org/jira/browse/GROOVY-9058?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16810895#comment-16810895
] 

Jochen Theodorou commented on GROOVY-9058:
------------------------------------------

a general comment about isDynamicTyped(). I think all uses of that method should be removed.
It is a left-over from pre-Groovy1 and was supposed to be used only if the type is Object
anyway. What is there now does no longer make sense since we are now using the metadata stuff.

>                 Key: GROOVY-9058
>                 URL: https://issues.apache.org/jira/browse/GROOVY-9058
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 2.5.6
>            Reporter: Mauro Molinari
>            Priority: Major
>
> Consider this Java class:
> {code:java}
> package test51;
> import java.util.List;
> public class Foo {
>     public List<Object[]> bar() { return null; }
> }{code}
>  and this Groovy class:
> {code:java}
> package test51
> import groovy.transform.CompileStatic
> @CompileStatic
> class Test51 {
>     protected void foo() {
>         List<Object[]> foo = new Foo().bar()
>         foo.each { row ->
>             def o = row[0]
>         }
>     }
>     
>     List bar() {
>     }
> }{code}
> This produces a compiler error because {{row}} is resolved as {{Object}} rather than
{{Object[]}}.
> A workaround is to declare {{row}} as {{Object[] row}} in the closure parameter list.
