My apologies, I only realized it after I invoked the Intellij formatter and that's why some more changes are showing. These are formatting changes.

@marcelomrwin Thanks for the PR!

I've added one inline comment (Sorry if I was unclear when we had a chat about this today morning. Hope it is clearer from the comment)

Besides that, is it possible to write automted test also for the scenario when the account client is disabled? I am thinking about the scenario like:

• User login
• Client account will be disabled
• Logout is triggered by going to the LogoutEndpoint without any parameters (In case that none of id_token_hint and client_id parameters is used, then the "System client" is used as the client during logout. And this system client is the account client). See calls to SystemClientUtil.getSystemClient for more details

Test scenario created and tested. Working as expected. I await your appreciation to ensure that the understanding was correct.
