Mauro Molinari created GROOVY-9058:
--------------------------------------

             Summary: each parameter type not correctly inferenced
                 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


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.
