>             Project: Groovy

>    Affects Versions: 3.0.6

> The following code will raise BME
> {code:java}
> import java.util.stream.*
> @groovy.transform.CompileStatic
> def x() {
>     IntStream.range(0, 2).forEach((Integer i) -> { assert 0 <= i && i < 2})
> }
> x()
> {code}
> but the following code works well:
> {code:java}
> import java.util.stream.*
> @groovy.transform.CompileStatic
> def x() {
>     IntStream.range(0, 2).forEach((int i) -> { assert 0 <= i && i < 2})
