The following code yields an "unnecessary test for null" hint for the code following a try/catch that ignores an exception.


  public static Class<?> foo (String s) {
    if (s == null) {
      try {
        return Class.forName("does.not.exist");
      }
      catch (ClassNotFoundException e) {
        // ignore
      }
    }

    if (s != null) {    // unnecessary test for null appears here
      return Object.class;
    }
    return String.class;
  }
