当调用onSaveInstanceState时，lite模式下的MapView崩溃

Question

当我使用LiteView模式的MapView时，在MapView对象上调用onSaveInstanceState（）方法会导致应用程序崩溃。

这是stacktrace：

java.lang.NullPointerException: Attempt to invoke interface method 'void com.google.maps.api.android.lib6.impl.bq.b(android.os.Bundle)' on a null object reference

代码示例

package ru.mail.sporttogether.fragments

import android.os.Bundle
import com.google.android.gms.maps.MapView
import ru.mail.sporttogether.mvp.MapPresenter
import ru.mail.sporttogether.mvp.PresenterFragment

abstract class AbstractMapFragment<T : MapPresenter> :
        PresenterFragment<T>() {
    protected lateinit var mapView: MapView

    override fun onSaveInstanceState(outState: Bundle?) {
        super.onSaveInstanceState(outState)
        mapView.onSaveInstanceState(outState)
    }

    override fun onLowMemory() {
        super.onLowMemory()
        mapView.onLowMemory()
    }

    override fun onStart() {
        super.onStart()
        mapView.onStart()
    }

    override fun onStop() {
        mapView.onStop()
        super.onStop()
    }

    override fun onPause() {
        mapView.onPause()
        super.onPause()
    }

    override fun onResume() {
        super.onResume()
        mapView.onResume()
    }

    override fun onDestroyView() {
        super.onDestroyView()
        mapView.onDestroy()
    }
}

在onCreateView（）方法中的其他片段中，我在MapView对象上调用onCreate（）和getMapAsync（）。 如果仅在lite模式下使用MapView，我有这个问题。 这是GP服务的内部错误吗？
