False Positive on S2583 when a @NotNull field is allowed to be null


I just made a simple sample to reproduce this. Pls take a look. I found the rule id is s2583.

package test;

import javax.validation.Valid;
import javax.validation.constraints.NotNull;

public class MyBean {

  public String name = null;
  public static void main(String[] args) {
    MyBean myBean = new MyBean();
    if (myBean.getName() != null){
      System.out.println("I am not null");
    }else {
      System.out.println("I am null");


  public String getName() {
    return name;

  public void setName(String name) {
    this.name = name;


Actually we can use this Bean inside our code to get/set without validation or use validation if it is needed, that’s depends on use cases.
