Should throw UnmatchedArgumentException when not all positional parameters are assigned to a field

[remkop]

For example:

// should throw exception when any command line args are specified
class ArityZero { @Parameters(arity = "0") List<String> params; } 

// should throw exception when two or more command line args are specified
class ArityOne { @Parameters(arity = "1") List<String> params; } 

// should throw exception when two or more command line args are specified
class SingleValue { @Parameters String str;  }

// should throw Ex for args: "A,B,C", "D", "E"
class Args { @Parameters(arity = "2..4", split = ",") String[] values; }
