>             Project: Groovy
>          Issue Type: Bug

>    Affects Versions: 4.0.2

> The following code can not run when STC is enabled:

> import java.util.stream.Collectors;
> @groovy.transform.CompileStatic
> def m() {
>     Map<String, Integer> map = new HashMap<>();
>     map.put("a", 1);
>     map.put("b", 2);
>     final Map<String, Integer> result =
>             map.entrySet().stream().collect(Collectors.toMap(e -> e.getKey(), e -> e.getValue(), (v1, v2) -> v1));
>     return result;
> }
> assert [a:1, b:2] == m();
> {code}
> Here are the error messages:
> {code:java}
