      Description

      With the sample program below, running with the arguments

      -a 0 -b 1 2 3 4

      causes the error:

      Unexpected 3 while processing options
      Usage:
      [-a <a1> [<a2> ...] -b <b1> <b2> [<b3> [<b4>]]]
      options
      a (-a) a [a ...]
      b (-b) b b [b [b]]

      I specified .withMinimum(2).withMaximum(4)
      The help is correct, but the value '3' is not added as a value.

      Note also that if for bOption, if you add two more defaults (uncomment them in the source)

      .withDefault("10000")
      .withDefault("1000000")

      an error is raised (incorrectly) on the first b value (i.e. 1 instead of 3) :

      Unexpected 1 while processing options
      Usage:
      [-a <a1> [<a2> ...] -b <b1> <b2> [<b3> [<b4>]]]
      options
      a (-a) a [a ...]
      b (-b) b b [b [b]]
