what Application are you trying to reproduce the issue. I tried rotating the device for couple of times, Issue not seen. Also provide Device you are using to reproduce the issue

Any Android 2.3.x, really. The application is a Beta version of an unreleased app.

This issie initially appeared on a Samsung Galaxy Ace with 2.3.3, but after testing it in an Android emulator, it also appeared. The dificulty to reproduce this is because it only seems to happen after a crash of the app (either by OOM or some other bug), and we Android tries to recreate the app, it crashes again with the "ClassNotFoundException when unmarshalling".

Also, we're having another crash similar to this, but in AppBarLayout.Behaviour:
