'readObject()' or 'writeObject()' not declared 'private'

Reports Serializable classes where the readObject or writeObject methods are not declared private. There is no reason these methods should ever have a higher visibility than private.

A quick-fix is suggested to make the corresponding method private.

Example:

public class Test implements Serializable {
  public void readObject(ObjectInputStream stream) {
    /* ... */
  }
}

After the quick-fix is applied:

public class Test implements Serializable {
  private void readObject(ObjectInputStream stream) {
    /* ... */
  }
}
