Android: Function onDestroy not called when stopping a service

If I close an Android service by calling stopSelf() the onDestroy() function of the service gets not called.

The attached example is a slightly modified minimal service example from KDAB.

Watch the application output over adb for example by calling adb.exe logcat | findstr /I kdab

Expected bahavior:

If you type "quit" in the message box, the service will be closed and the destructor function onDestroy() gets called.

Actual bahavior:

The service gets closed but the onDestroy() function is not executed.
