Review Comment:
I think "int" should be "Integer". The closure params are passed as
objects, so there is no optimization like `Consumer` versus `IntConsumer`.

> Key: GROOVY-10682
> URL: https://issues.apache.org/jira/browse/GROOVY-10682
> Project: Groovy
> Issue Type: Improvement
> Components: groovy-jdk
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Minor
>
> Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> void test(int[] ints) {
> ints.eachWithIndex { value, index ->
> println "$index: ${value.doubleValue()}"
> }
> }
> test(0,1,2,3,4,5)
> {code}
> Compiler reports "[Static type checking] - Cannot find matching method
> java.lang.Object#doubleValue()"
> {{eachWithIndex}} is only provided for reference types, so "value" is seen as
> Object by the type checker.
