Is there any unboxing avoid null check

[samanhappy]

like f(id) in below code block

public class Test {
  public static Integer id;

  public static void f(int i) {}

  public static void main(String[] args) {
    f(id);
  }
}

Types are hard for our tool https://checkstyle.org/writingchecks.html#Limitations

In more complicated case we will not be able to get to know actual type of variable.
