          Issue Type: Bug
          Components: Static Type Checker
            Reporter: Thodoris Sotiropoulos


I have the following program

{code}
import java.util.*;
import java.util.stream.*;
import java.util.function.*;


class Main {
  static final void test(DoubleStream x, ObjDoubleConsumer<Boolean> y,
                         BiConsumer<Boolean, Boolean> z) {
        Spliterator.OfDouble d = null;
        StreamSupport.doubleStream(d, x.collect(
            () -> true, y::accept, z::accept));
  }
}
{code}

h3. Actual behavior

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 10: [Static type checking] - Cannot find matching method 
java.util.stream.StreamSupport#doubleStream(java.util.Spliterator$OfDouble, U). 
Please check if the declared type is correct and if the method exists.
 @ line 10, column 9.
           StreamSupport.doubleStream(d, x.collect(
           ^
