Brian Stansberry commented on AS7-2017:
---------------------------------------

Extended mode for -D would be a fairly significant on-going maintenance burden. There's no way to include help text for every system property that any component of the AS may support. And any such list we prepared could easily fall out of date. We could limit the coverage to a more limited set, i.e. some the core AS ones, perhaps some of the ones we use *by convention only* in our standard config files.  But those could also fairly easily fall out of date. Documenting these things in the on-line docs and not in the script output makes it simple to correct any mistakes that are discovered. Correcting --help text requires a new release.

Basically, the more expansive the desired list of system properties is, the more I dislike the feature. :-)

There are a couple classes (ServerEnvironment, HostControllerEnvironment) that deal with some of the really basic properties that are read right at the beginning of boot; things like jboss.server.base.dir etc. Those classes are highly stable. It would be pretty safe to expose those properties in the --help text.

> This should show all of the options as in the past like -G -m -u -b and maybe an extended mode shows all of the possible -D options that can be passed in.
