      Description

      I have the following program

      class A<T> {
        T x;
        A(T x) {
          this.x = x;
        }
      }
      
      public class Main {
        public static void main(String[] args) {
          bar((new A<>("")).x);
        }
        public static void bar(String x) {}
      }
      

      Actual Behaviour

      I get the following compile-time error

      org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
      test.groovy: 11: [Static type checking] - Cannot find matching method Main#bar(T). Please check if the declared type is correct and if the method exists.
       @ line 11, column 5.
             bar((new A<>("")).x);
             ^1 error
      
      

      Expected Behaviour

      Compile successfully
