Parameter value "-something" misinterpreted as a parameter. CLI_1_BRANCH build.xml doesn't work. No Javadoc for HelpFormatter!. Options should not be able to be added more than once. Infinite Loop in Command-Line processing. Documentation errors. A weakness of parser. CommandLine.getOptionValue() behaves contrary to docs. Dependecy on commons-lang-2.0 but commons-lang-1.0 is obtained. Document enhancement. Error parsing option arguments. HelpFormatter doesn't function correctly for options with only LongOpt. Line separator as first char for helpformatter (footer) throws exception. Missing arguments in HelpFormatter.renderOptions(..). Only long options without short option seems to be noticed. Parser breaks up command line parms into single characters. Passing properties in Parser does not work for options with a single argument. Wrong usage summary. clone method in Option should use super.clone(). clone() method doesn't fully clone contents. HelpFormatter doesn't sort options properly. Remove the Commons Lang dependency. Setting description of a Option.
