New roles not committed until restart of server?

Question

Hi all,
I'm working with WL 7.0 and have run into a problem as follows (all the
steps are executed programmatically).
1. Create a new Group
2. Create a new Role that depends on the new group.
3. Create a new User
4. Add the user to the new group
I would now expect that a call to isCallerInRole() with the newly created
role for the new user would return 'true'. However, this doesnt't work until
the server has been restarted. Anyone know why this is the case?
Any help greatly appreciated.

Oh yea, You are right. It would be a kind of workaround.  The weird part of this is that when i look at secpol.msc in local policy -> "User Rights Assignment" -> "Log on as a service" propertise, there is no user name, instead
of that is "S-1-5-21..." GUID . When i add normal user name there eg. "Sql_services" then services start normally. 
Funny part is that this GUID is none of my list from "wmic useraccount get name, sid" .
Why windows is deleting my user and inserting there some weird GUID ?? 
BTW i actually noticed that it happening also at normal server work, without restart, when i stop SQL service then i cannot start it again :/
