----------------------------------------------

             Summary: STC is looking for the wrong constructor reference
                 Key: GROOVY-10971
                 URL: https://issues.apache.org/jira/browse/GROOVY-10971
             Project: Groovy
          Issue Type: Bug
            Reporter: Thodoris Sotiropoulos


I have the following program

{code}
class Foo {
  Foo(String d) {}
}

class Main {
  static final void test() {
        def x = java.util.stream.Collectors.groupingBy(Main::m) // works;
        def y = java.util.stream.Collectors.groupingBy(Foo::new) // fails;
  }

  static Foo m(String x) { return null; }
}
{code}

h3. Actual behavior

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 8: [Static type checking] - Cannot find matching constructor 
Foo(java.lang.Object)
 @ line 8, column 56.
   .stream.Collectors.groupingBy(Foo::new)
                                 ^

1 error
{code}

h3. Expected behavior

Compile successfully

Tested against master (commit: 46722e7147ed529fe8817660617ac6af98ad6f54)
