I have the following code

import java.util.function.*;

class Main {
  static final void test() {
    String str = "foo"
    LongConsumer y = str.chars().asLongStream().summaryStatistics();
    str.chars().asLongStream().summaryStatistics().andThen(y); // Does not work

    str.chars().asLongStream().summaryStatistics().andThen((LongConsumer) y); // it works
  }
}
{code}

h3. Actual behavior

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 8: [Static type checking] - Reference to method is ambiguous. Cannot choose between [java.util.function.IntConsumer java.util.function.IntConsumer#andThen(java.util.function.IntConsumer), java.util.function.LongConsumer java.util.function.LongConsumer#andThen(java.util.function.LongConsumer)]
 @ line 8, column 5.
       str.chars().asLongStream().summaryStatistics().andThen(y); // Does not work
       ^

1 error
{code}

h3. Expected behavior
