Persistance Error creating new Group from UserManager (ResourcerResolver.commit())

I have a service I call on to create a new approver group for a user if it doesn't already exist, here's the whole method:

public void updateApproverGroup(Author person) { try { Map<String, Object> param = new HashMap<String, Object>();         param.put(ResourceResolverFactory.SUBSERVICE, "WriteService"); ResourceResolver resourceResolver = resolverFactory.getServiceResourceResolver(param);       log.info(resourceResolver.getUserID());     session = resourceResolver.adaptTo(Session.class);     userManager = resourceResolver.adaptTo(UserManager.class);     String groupName = person.id + "Approvers"; //does the group exist? Group group = (Group) userManager.getAuthorizable(groupName); if(group == null) { //create the group group = userManager.createGroup(groupName,new SimplePrincipal(groupName),"/home/groups/news"); log.error(group.getPath()); } resourceResolver.commit(); } catch (Exception e) { log.error(e.getMessage()); for(int i  = 0; i < e.getStackTrace().length; i++) { log.error(e.getStackTrace()[i].toString()); } return; } }

My catch block catches an exception, here's the first few lines from my console

writeuser has full rights for the entire repository, so it doesn't seem like a permissions issue. 

The group that it puts in the console at the second line isn't showing up in the repo either (as expected).

I've also tried creating the usermanager from a jackrabbitsession I adapted from the resource resolver, with no luck. (that method is detailed here).

See this community article where we created both AEM users and groups using the Jackrabbit API:

I have seen that behaviour myself - that looks almost like a bug. Sometimes (like this case) so called deprecated APIs work better. This is one of those cases.

This worked when I swapped the resourcerevolver to resolverFactory.getAdministrativeResourceResolver(null); (as opposed to using getServiceResourceResolver).

I know that getAdministrativeResourceResolver() is deprecated, but I'll use it for now--are there details on how these differ? Is it as simple as using the admin user? How would the admin user differ from a system user will full rights?

I tried that both before and after the userManager.createGroup() with no success, the log is essentially exactly as before.

can you use resourceResolver.refresh() before commit() and try

Do something like this, I think subservice logic is not working in AEM 6.1 (It used to work in AEM6.0)

@Reference ResourceResolverFactory rrfac; ResourceResolver rr=null; Map<String,Object> authInfo = new HashMap<String,Object>(); //Change this code in future to use read only user authInfo.put(ResourceResolverFactory.USER_IMPERSONATION,"WriteUser"); rr = rrfac.getAdministrativeResourceResolver(authInfo); //Your Logic rr.commit();
