In SystemJobService, it can expect null, and able to tolerance null from WorkManagerImpl.getInstance, due to auto-backup reason.
@Override
public void onCreate() {
super.onCreate();
mWorkManagerImpl = WorkManagerImpl.getInstance(getApplicationContext());
if (mWorkManagerImpl == null) {
// This can occur if...
// 1. The app is performing an auto-backup. Prior to O, JobScheduler could erroneously
// try to send commands to JobService in this state (
// Application#onCreate nor ContentProviders have run, WorkManager won't be
// initialized. In this case, we should ignore all JobScheduler commands and tell it
// to retry.
But, current WorkManagerImpl.getInstance(Context context) implementation is that, it will never return null but throw IllegalStateException.
Isn't there's conflict among these 2 SystemJobService.onCreate logic, and WorkManagerImpl.getInstance logic?

Fix for JobScheduler calls when backup is in progress.
The original fix (ag/Ia1604b7c4b98f6b31869e1161a0c1efce7fe46f2) relied
on a null-check, but the new version of WorkManager.getInstance(Context)
with the Context param doesn't return null; it throws an Exception. This
CL updates the three places where we explicitly check for the return value
internally:
1. SystemJobService (the main place where this would manifest)
2. RescheduleReceiver
3. WorkManagerTestInitHelper (for consistency)
Fixes: 135858602
Test: Ran existing tests

Thanks you so much for the speedy fixed!
May I know when will it be ready for production? As, currently, this IllegalStateException is impacting our users.

Hello, please look for this later in the week. If you want to work around this bug specifically and don't need on-demand initialization, you can use the old (deprecated) WorkManager.getInstance() method for now.
Description
Component used: Paging3 Version used: alpha06 Devices/Android versions reproduced on: Android 7.1
I'm presenting a list of items using data from a room DB.
Note: The page size is intentionally low to try to debug paging issues, but is higher in production code.
The pager flow is used to produce
PagingDatapassed to aPagingAdapter.The RecyclerView uses a simple LinearLayoutManager.
Everything work mostly fine except that that latest entry may never be loaded while scrolling (especially when scrolling slowly). The PagingData properly provides a placeholder that is shown in the list, but it never trigger the loading of the last data, and so never replace the placeholder when reaching the end of the list.
