Component used: work-runtime
Version used: 1.0.0-alpha08
Devices/Android versions reproduced on:   Moto G5s Plus, Android 7.1.1 / Huawai P20 lite, Android 8.0.0


We can reproduce a crash of the workmanager on some devices.
In our code we enqueue a UniqueWork with ExistingWorkPolicy.REPLACE, as soon as it finishes with State.SUCEEDED we enqueue it again. There is always only one job at the time.

After about 100 jobs the workmanager crashes with: java.lang.IllegalStateException: Apps may not schedule more than 100 distinct jobs.

It looks like the workmanager does not prune the finished jobs fast enough, and they count as 'sheduled' job, even if they are finished?

The crash is reproducible on the Moto G5s Plus and Huawai P20 lite. But it behaves very inconsistent, sometimes it occurs on the first run, sometimes only after a few restarts of the app. But we cannot reproduce it on the Pixel 2 XL or the emulator.

Calling pruneWork() before enqueue() doesn't fix the problem.
Reducing the result lifetime by calling keepResultsForAtLeast(..) doesn't work as well.

We provided a sample app which triggers the issue.
