Wrong classloader can be set in the current thread

See a topic on support forum: link

CUBA version: 7.0.6
Addon version: 0.4

Test case

1. Create a global event to fire
2. Create a service that will fire the event
3. Extend main window and subscribe for the event
4. Create any entity and open it in editor in event listener method
5. Create scheduled task that will trigger the service
