             Summary: Native lambdas with @CompileStatic at method level
                 Key: GROOVY-8493
                 URL: https://issues.apache.org/jira/browse/GROOVY-8493
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.6.0-alpha-3
            Reporter: Paul King


This code:
{code}
import groovy.transform.CompileStatic
import java.util.stream.Collectors

@CompileStatic
class Main {
    static void main(String[] args) {
        assert [2, 3, 4] == [1, 2, 3].stream().map(e -> e.plus 1).collect(Collectors.toList())
    }
}
{code}
works and produces a native lambda with the following bytecode within it's {{doCall}} method:
{code}
INVOKESTATIC org/codehaus/groovy/runtime/dgmimpl/NumberNumberPlus.plus (Ljava/lang/Number;Ljava/lang/Number;)Ljava/lang/Number;
{code}
but moving the {{@compileStatic}} to the {{main}} method only, results in the following error:
{code}
java.lang.NoSuchMethodError: java.lang.Number.plus(Ljava/lang/Number;)Ljava/lang/Number;
{code}
and the following bytecode in the {{doCall}} method:
{code}
INVOKESTATIC java/lang/Number.plus (Ljava/lang/Number;)Ljava/lang/Number;
{code}
