Non-serializable class with 'serialVersionUID'

Reports non-Serializable classes that define a serialVersionUID field. A serialVersionUID field in that context normally indicates an error because the field will be ignored and the class will not be serialized.

Example:

  public class IWantToSerializeThis {
    private static final long serialVersionUID = 2669293150219020249L;
  }
