'android.os.Looper.quit()' on a null object reference - Android O

First Activity of my Application starts a STICKY sevice that I'm using for creating notifications. Recently I've noticed a bug on Android O devices: when user starts an Application and then after a few seconds application was in background state the user gets this excpetion:

Still not sure about the reason of exception, but I just switched from IntentService to Service and now it works fine.
