Since this commit https://github.com/windup/windup/commit/53c5fe5815, Windup ignores archives that are comprised only of well-known 3rd party packages (e.g. org.jboss). I believe that this is a wrong default if only a single archive is being analyzed.

Note that this isn't equivalent to "only a single archive was passed on the command line". That single archive that was passed on a command line could have been a WAR or EAR containing 3rd party JARs, in which case multiple archives would actually be analyzed. However, if the single archive that was passed on the command line doesn't contain any other archives, that would be the case that only one archive is analyzed.
