commons-cli bug一粒

commons-cli 1.2里关于OptionGroup有一个bug

上代码
list [-t file type| -n file name]

OptionGroup optionGroup = new OptionGroup();
optionGroup.addOption(new Option("t", "type", true, "file type"));
optionGroup.addOption(new Option("n", "name", true, "file name"));

比如第一次解析了list -t以后
第二次解析list -n就会报AlreadySelectedException错，说
The option 'n' was specified but an option from this group has already been selected: 't'

跟踪了半天代码，然后查了官网jira issue，发现这个是1.2版的一个issue，然后再1.3-SNAPSHOT版里解决了。 :-(
