    Description

      Javac doesn't issue a warning if a serialVersionUID is present in an enum or an anonymous subclass. It should issue a warning, since the serialVersionUID of any enum or anon subclass of enum is defined to be 0L.

      Compiling the following with -Xlint:all generates no warnings.

      It might be reasonable to have this warning controlled by the "serial" lint option, that is, enabled via -Xlint:serial.

      ----- Guy.java -----

      enum Guy {
          TOM {
              private static final long serialVersionUID = 4290774380558885855L;
          },

          DICK {
              private static final long serialVersionUID = -6849794470754667710L;
          },

          HARRY {
              private static final long serialVersionUID = -9172774392245257468L;
          };

          private static final long serialVersionUID = 1360826667806852920L;
      }
