it.tidalwave.thesefoolishthings.examples.extendedfinderexample.PersonFinderImpl2a is Serializable; consider declaring a serialVersionUID
 This class implements the Serializable interface, but does
  not define a serialVersionUID field. 
  A change as simple as adding a reference to a .class object
    will add synthetic fields to the class,
   which will unfortunately change the implicit
   serialVersionUID (e.g., adding a reference to String.class
   will generate a static field class$java$lang$String).
   Also, different source code to bytecode compilers may use different
   naming conventions for synthetic variables generated for
   references to class objects or inner classes.
   To ensure interoperability of Serializable across versions,
   consider adding an explicit serialVersionUID.
