Description

I have the following code

class Main {
  static final void test() {
    double[] x = Tuple.tuple(org.codehaus.groovy.runtime.ArrayGroovyMethods.max((double[][]) null, { -> 1 })).getV1();
  }
}

Actual behavior

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 3: [Static type checking] - Cannot assign value of type (java.io.Serializable or java.lang.Cloneable) to variable of type double[]
 @ line 3, column 18.
       double[] x = Tuple.tuple(org.codehaus.groovy.runtime.ArrayGroovyMethods.max((double[][]) null, { -> 1 })).getV1();
                    ^

1 error

Expected behavior

Compile successully
