Component used: Paging:2.0.0-rc01
Version used: AndroidX 1.0.0-rc02, Paging:2.0.0-rc01

I use Room to load from database and display in Recyclerview using Paging library. The list will crash randomly if I scroll the list up and down very fast. Not every time but I can reproduce it easily, especially if the list is large.

Below is the crash stack:
java.lang.IndexOutOfBoundsException: Index out of bounds - passed position = 447, old list size = 240
