[wildfly-dev] AddStepHandler can't add content to overlay

[Stuart Douglas]

Can you elaborate on why you need this?

In your previous thread you mentioned user provided content and I 
suggested that they could use overlays, however this would require the 
user to install the overlays rather than the subystem.

Looking at your example it looks like you are adding 
keycloak-server.json as an overlay, and I can't help but wonder why?

I would guess that you are doing this to allow a deployment to read a 
file that is external to the deployment to be read from the class 
loader? If that is the case then I think there are better ways you can 
approach this (e.g. adding a resource loader to the module that can 
access this file).
