This report is inactive by default. Condition (x != null) or (x == null) when x cannot be null: the first condition is always true and the second is always false

Example:

class C {
  void m() {
    String s = new String("abc");
    if (s != null) {
      int n = s.length();
    }
  }
}

Action: Make sure that the annotations are correct, as the condition is considered redundant based on the existing annotations. In particular, check the annotation of any input parameters and fields of the current method, as well as the annotations of any method called directly by the current method, if relevant. If the annotations are correct, you can remove the redundant case.
