Balz Guenat updated CLI-300:
----------------------------
Description:
Assuming there is a short option with {{foo}} with one argument. Trying to
parse a token like {{-foo=bar}} results in an UnrecognizedOptionException.
The same scenario works fine if the short option is only one char long.
The reason is an if-statement in {{DefaultParser.handleShortAndLongOption()}}
(line 543 in v1.4), which checks {{opt.length() == 1}} before checking if the
option exists. IMO, this check should instead be {{isShortOption(opt)}}.
The below code demonstrates the issue.
{{Options options = new Options();}}
{{Option option = Option.builder("foo").hasArg().build();}}
{{options.addOption(option);}}
{{String[] args = new String[] \{"-foo=bar"};}}
{{DefaultParser parser = new DefaultParser();}}
{{CommandLine cmdLine = parser.parse(options, args);}}
{{assertEquals("bar", cmdLine.getOptionValue("foo"));}}
