Instead of

      /* YYPACT[STATE-NUM] -- Index in YYTABLE of the portion describing
       STATE-NUM.  */
      private static final byte yypact_[] = yypact_init ();
      private static final byte[] yypact_init ()
      {
        return new byte[]
        {
          25,    -7,    -8,    37,    -8,    40,    -8,    20,    -8,    61,
          -8,    -8,     3,     9,    51,    -8,    -8,    -2,    -2,    -2,
          -2,    -2,    -2,    -8,    -8,    -8,     1,    66,    66,     3,
           3,     3
        };
      }

generate

    /* YYPACT[STATE-NUM] -- Index in YYTABLE of the portion describing
       STATE-NUM.  */
      private static final byte[] yypact_ =
      {
          25,    -7,    -8,    37,    -8,    40,    -8,    20,    -8,    61,
          -8,    -8,     3,     9,    51,    -8,    -8,    -2,    -2,    -2,
          -2,    -2,    -2,    -8,    -8,    -8,     1,    66,    66,     3,
           3,     3
      };

I have no idea what motivated the previous approach.
