[TYPO3-mvc] Fe Users don't have access for their personal data on TYPO3 6.2

[Dmitry Vasiliev]

Hi list,

In my extension, I make access to personal data for fe_users as 
described in this article
http://blog.schreibersebastian.de/2012/06/erweiterung-der-fe_users-mittels-extbase-1-3/

I am using namespaces like "namespace TYPO3\MyExt\Service" and classes like
"class AccessControlService implements \TYPO3\CMS\Core\SingletonInterface".

And it works on TYPO3 6.1, but don't work on TYPO3 6.2 My Fe Users don't 
have access for their personal data.
What has changed in TYPO3 6.2, it stopped working?

I tried to change [FE][loginSecurityLevel] from RSA to normal, it does 
not help.

How to solve this problem?

Kind regards,
Dmitry Vasiliev
