Description

1. First at all, your testAmbiguousLongWithoutEqualSingleDash does not lead to a AmbiguousOptionException

1. For this same test, if I replace the deprecated OptionBuilder with Option.Builder as follows

   options.addOption(Option.builder().option("f").longOpt("foo").optionalArg(true).build());
   options.addOption(Option.builder().option("b").longOpt("bar").optionalArg(false).build());
   

   the test leads to a NPE

   java.lang.NullPointerException
   	at xx.DefaultParser.handleShortAndLongOption(DefaultParser.java:476)
   	at xx.DefaultParser.handleToken(DefaultParser.java:535)
   	at xx.DefaultParser.parse(DefaultParser.java:714)
