>                 URL: https://issues.jboss.org/browse/FORGEPLUGINS-162
>             Project: Forge Plugins/Addons
>          Issue Type: Bug
>          Components: JBoss AS Plugin
>            Reporter: Antonio Goncalves
>            Priority: Critical
>
> I've installed the latest version of Forge (2.4.2-SNAPSHOT) and JBoss AS Addon :
> {code}
> [demo]$ addon-list
> Currently installed addons:
> ...
> org.jboss.forge.addon:as,2.0.0-SNAPSHOT
> org.jboss.forge.addon:as-jboss-as7,2.0.0-SNAPSHOT
> org.jboss.forge.addon:as-jboss-wf8,2.0.0-SNAPSHOT
> org.jboss.forge.addon:as-spi,2.0.0-SNAPSHOT
> {code}
> Things work kind of ok, I manage to start JBoss, deploy app, but once in a while (I don't know how to reproduce it) I get a NPE on the logs, and then, all the {{as}} commands disappear (not TAB completion), and that's the end of the add-on. Even restarting Forge doesn't help. I need to remove and re-install the addon.
