I had this problem once too, but that is because initially your database has
no users.
Try nuking the database first "ant nuke" and then try the following steps.

Once you are in dev mode and on the home page, click on the "Populate
Database" button. This basically adds the users and sets their Roles
appropriately. Otherwise, what happens is the moment you log in and the
database is empty, the username gets added to the database as a GUEST.
This is the reason you keep getting matt@xxxxxxxxxxx as GUEST rather than
ADMIN.

OK seems like this is an issue I found out last night while fixing something
else. I'm not quite sure why this happens, but I think it's because Set<T>
does not implement either a Serializable or IsSerializable. The only way I
can think of is to change Set<Achievement> to HashSet<Achievement> as
HashSet is a concrete class that implements Serializable. I haven't fully
tested this, but I believe this should fix the bug. Please note that by
changing the appropriate service in shared, you may have to change the
corresponding method interface on the ServiceAsync and ServiceImpl.

If Jens is unsure as to how the services work, then could Scott/Matt change
them as I can't commit any changes I make via proxy. :(
