----------------------------------
I was able to recreate this by enabling self-registration and visiting the following URL:
curl -F:name=reader -Fpwd=ourReader -FpwdConfirm=ourReader -F"desc=Read only access" http://localhost:8080/system/userManager/user.create.html
The exception is not shown in the logs. It comes back as part of the response.

----------------------------------
I see this NPE showing up without forwarding to /system/userManager/user.create.html but going directly to it. `createUser(..)` is returning a null object. The user is created as shown by subsequent create-calls that return with "user exists." I'm digging into why this is happening.

Carl Hall commented on SLING-2465:
----------------------------------
The problem here is the JCR session is bound to the `anonymous` user and that user can't see the user that is created. We could use the submitted `principalName` instead of using user.getID(). I assume the two are the same but I need to check if this okay to do.

----------------------------------------
By the way. I have selfRegistration enabled. Seems this issue appears only, when Anonymous tries to create a new user.

----------------------------------
After talking with Justin, we decided to impersonate the session with the new user but that breaks down if the impersonated session is closed before the User is returned. Taking the conversation to dev@sling to figure this out.
