Duplicated options are wrongly accepted in Apache Commons Cli

Question

When I repeat some options by command line are wrongly accepted

private static void buildMyCliOptions() { 
   optionsMyAdd.addOption(Option.builder()
     .longOpt("my-address")
     .argName("property=value")
     .hasArg()
     .desc("Specify Address")
     .required()
     .build());

   optionsMyAdd.addOption(Option.builder()
     .longOpt("my-port")
     .argName("property=value") 
     .hasArgs()
     .valueSeparator()
     .desc("Specify port")
     .required()
     .build());

} 

tempOptions = ParseCommand.getOptionsMyAdd();
commandLine = cmdLineParser.parse(tempOptions, ParseCommand.args,true);

for instance: add --my-address=addr1 --my-address=addr2 --my-port=port1

But I would like an error for --my-address=addr2, since it is duplicated.
