Alexander Klimetschek commented on OAK-2956:
--------------------------------------------
Problem (after I deleted the groups and it still didn't want to install) was
that the UUID was wrong, I chose it myself (manually changed a few chars), but
in fact it is based on the authorizable ID, and because I changed that, it had
to be adapted as well. So the only way is to create the user on the server and
then copy the content with the right UUID into the package. Unfortunately, one
has to provide a jcr:uuid in the .content.xml – it would be nice if this could
be left out. Same for rep:principalName (so much duplication in the sources).

> meaning {{userManager.getAuthorizable(id)}} returned null.
> While the use case might not be something to support (this happens during
> development, changing group names/details until "right"), at least the NPE
> should be guarded against and a better error message given.
> Looking closer, it seems like a difference between
> {{UserManager.getAuthorizable(Tree)}} (called earlier in the method) (I
> assume using UUID to look up the existing group successfully) and
> {{UserManager.getAuthorizable(String)}} (using the rep:authorizableId to look
> up the user, failing, because it changed).
