Greg Toombs updated CLI-251:
----------------------------
Description:
In WriteableCommandLineImpl.java, the code after this comment:
// ensure that all parent options are also added
ends up rejecting what should be valid command-line args. If you make a group
and use it as a child in more than one parent, which is a wholly reasonable
usage of the API, I think the child only registers one parent and then the "int
present" counting goes over its maximum and the args are rejected, because
hasOption returns a false positive.
