Running in a debugger confirms that the HDScanner is treating each file inside the war as a new deployment. This doesn't happen with -Djboss.as.deployment.ondemand=true because there's a bug in the way profiles are configured for HD scanning. It only gets turned on via this bit in ProfileServiceBootstrap.start(...)
 
      // Enable modification checks on all mutable profiles 
      for(ProfileKey key : profileService.getActiveProfileKeys())
      {
         try
         {
            Profile profile = profileService.getActiveProfile(key);
            if(profile.isMutable() && profile instanceof MutableProfile)
            {
               ((MutableProfile) profile).enableModifiedDeploymentChecks(true);
            }
         }
         catch(NoSuchProfileException ignore) { }

 
With -Djboss.as.deployment.ondemand=true when that code executes, the profiles for the on-demand wars are not yet "active" so the enableModifiedDeploymentChecks(true) call is never made.  With -Djboss.as.deployment.ondemand=false the profile is active and the profile is exposed to the HDScanner.
