> Key: CLI-317
> URL: https://issues.apache.org/jira/browse/CLI-317
> Project: Commons CLI
> Issue Type: Bug
> Components: Parser
> Affects Versions: 1.5.0
> Reporter: Philippe Bastiani
> Priority: Critical
> Labels: exception
>
> # First at all, your *testAmbiguousLongWithoutEqualSingleDash* does not lead
> to a AmbiguousOptionException
> # For this same test, if I replace the deprecated OptionBuilder with
> Option.Builder as follows
> {code:java}
> options.addOption(Option.builder().option("f").longOpt("foo").optionalArg(true).build());
> options.addOption(Option.builder().option("b").longOpt("bar").optionalArg(false).build());
> {code}
> the test leads to a NPE
> {code:java}
> java.lang.NullPointerException
> at xx.DefaultParser.handleShortAndLongOption(DefaultParser.java:476)
> at xx.DefaultParser.handleToken(DefaultParser.java:535)
> at xx.DefaultParser.parse(DefaultParser.java:714)
> at xx.DefaultParser.parse(DefaultParser.java:677)
> at xx.DefaultParser.parse(DefaultParser.java:654)
> {code}
> _Note_ : tested with Github code (January 22, 2023)
