ConnectivityExtension: ConnectivityExt jar file not present When using adb logcat to get debug messages from my phone, I get many of those lines:

04-23 18:16:51.085  1428  1951 W ConnectivityExtension: ConnectivityExt jar file not present
04-23 18:16:51.187  1428  1951 W ConnectivityExtension: ConnectivityExt jar file not present
04-23 18:16:51.658  1428  1951 W ConnectivityExtension: ConnectivityExt jar file not present


Where is this coming from?
What can I do to get rid of those message?

I'm running LineageOS 14.1-20180314-crackling (Android 7.1.2) on a Wileyfox Swift. I don't have any google apps (nor google play services) installed.
After some searching around, it turns out ConnectivityExt is a proprietary Qualcomm file (source - you can see that it is included in the proprietary-files.txt in LineageOS), related to the Qualcomm package com.qualcomm.qti.tetherstatsextension.tetherstatsreporting. I found some code  for this here, line 107 onwards. As it seems to be about TetherStatsReporting, maybe it is related to hotspot? Considering it is proprietary I do not think you can do anything about it.
