JOC writes log endlessly for SessionNotExistException

Current Situation

• When the JOC Cockpit throws an exception SessionNotExistException it starts writing log endlessly in YYYY_MM_DD.stderrout.log

How to reproduce

• One best condition to reproduce the issue is adding/Removing user or roles that update the shiro.ini file.
• Login to the JOC Cockpit and switch to Manage Accounts.
• Create or Delete a user/role
• Open the new browser tab and login to the JOC Cockpit just to reflect the Shiro.ini changes.
• This will log out the previous User session (older tab) and throws the SessionNotExistException.
• Open the file YYYY_MM_DD.stderrout.log, the log is written endlessly with the same exception.

Desired Behavior

• The JOC Cockpit should not write log YYYY_MM_DD.stderrout.log endlessly when such an exception occurs.
