Description

I have the following program

class A<T> {
  <T> T foo(T t) { return t; }
}


class B {

  void bar(int x) {}

  void test() {
    int x = (new A<String>()).foo(1);
  }
}

Actual behaviour

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 11: [Static type checking] - Cannot find matching method A#foo(int). Please check if the declared type is correct and if the method exists.
 @ line 11, column 13.
       int x = (new A<String>()).foo(1);
               ^

1 error

Expected behaviour

Compile successfully
