• Type: Bug
• Status: Closed

Description

The following code will raise BME

import java.util.stream.*

@groovy.transform.CompileStatic
def x() {
    IntStream.range(0, 2).forEach((Integer i) -> { assert 0 <= i && i < 2})
    // IntStream.range(0, 2).forEach(i -> { assert 0 <= i && i < 2}) // raise BME too
}

x()

but the following code works well:

import java.util.stream.*

@groovy.transform.CompileStatic
def x() {
    IntStream.range(0, 2).forEach((int i) -> { assert 0 <= i && i < 2})
}

x()
