>     Foo (T f) {
>       this.f = f;
>     }

> class Main  {
>   public static void main(String[] args) {
>       Foo<Integer> x = new Foo<>(1);
>       assert x.f < 10 == true; // does not compile
>       m(x);
>   }  public static void m(Foo<Integer> x) {
>       assert x.f < 10 == true; // compiles fine
>   }
> }
> {code}
> the type checker reports:
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Test.groovy: 11: [Static type checking] - Cannot find matching method java.lang.Object#compareTo(int). Please check if the declared type is correct and if the method exists.

> I would expected that the program above compiles successfully.
