Unable to activate instance of type Java.Lang.Runnable from native handle

I am getting recently so many Java errors. is there anyone else experience such exceptions? Full stacktrace looks like below. I am not able to understand and i am not able to reproduce myself but i can see in my app center logs, many of the users with different phone types experience this.

I suspect about opendjk. before i was using javajdk and recently i changed it using openjdk. Other big changes are Xamarin forms 3.4 (not using 3.5 yet), Android support libraries 8.1 and Syncfusion libraries. Does anyone have any clue what could be the problem?
