Description

I have the following program

import java.util.List;
import java.util.function.Predicate;


class Main {
  static final <T> void test() {

    List<T> x = null;
    Predicate<? super T> y = x::add;

  }
}

Actual behavior

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 9: Failed to find method 'add(T)' for the type: java.util.List<T> @ line 9, column 30.
       Predicate<? super T> y = x::add;
                                ^

1 error

Expected behavior

Compile successfully
