java.util.concurrent.RejectedExecutionException in Crashlytics #2013

Mikhael-Danilov · 2020-09-29T11:59:53Z

Describe your environment

Android Studio version: 4.0.1
Firebase Component: Crashlytics
Component version: 17.2.1

Describe the problem

Crashes on Huawei devices with api levels 24, 26, 27, 28, 29

java.util.concurrent.RejectedExecutionException: at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution (ThreadPoolExecutor.java:2104) at java.util.concurrent.ThreadPoolExecutor.reject (ThreadPoolExecutor.java:848) at java.util.concurrent.ThreadPoolExecutor.execute (ThreadPoolExecutor.java:1413) at java.util.concurrent.Executors$DelegatedExecutorService.execute (Executors.java:624) at com.google.android.gms.tasks.zzc.zza at com.google.android.gms.tasks.zzq.zza at com.google.android.gms.tasks.zzu.zza at com.google.android.gms.tasks.zze.run at java.util.concurrent.ThreadPoolExecutor.processTask (ThreadPoolExecutor.java:1187) at java.util.concurrent.ThreadPoolExecutor.runWorker (ThreadPoolExecutor.java:1152) at java.util.concurrent.ThreadPoolExecutor$Worker.run (ThreadPoolExecutor.java:641) at com.google.firebase.crashlytics.internal.common.ExecutorUtils$1$1.onRun (ExecutorUtils.java:60) at com.google.firebase.crashlytics.internal.common.BackgroundPriorityRunnable.run (BackgroundPriorityRunnable.java:27) at java.lang.Thread.run (Thread.java:784)

Steps to reproduce

I was not able to reproduce it locally but it happens regularly in production.

The text was updated successfully, but these errors were encountered:

Does Anyone found a solution for this issue?

Hi folks - wanted to just ping this thread and let you know we're looking into this and I'll let you know when I have more information.

Same here, this is the highest crash in our app, mostly coming from Samsung and Huawei devices.
@mrwillis21 do you think there's a chance this might be caused by a problem on transitive dependencies? (e.g. some dependency update transitively updated something else (usually play-services-related) which crashlytics depends on)

mrwillis21 · 2020-10-27T15:29:58Z

@sergiomarqmoura I'm not sure yet, but if you could post the stack trace you're seeing, it would help track it down. 😄

sergiomarqmoura · 2020-10-27T16:06:16Z

Hey @mrwillis21 , this is the status so far:

In the beginning, we had firebase-crashlytics:17.2.2, where the following dependencies were using different versions other than the ones Crashlytics is expecting (due to gradle resolving a higher version from one other dependency):

play-services-tasks: Using 17.1.0 instead of 17.0.0 (the one crashlytics depends on)
play-services-basement: Using 17.1.1 instead of 17.0.0 (the one crashlytics depends on)

With this configuration, the following crash was appearing:

java.util.concurrent.RejectedExecutionException: 
  at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution (ThreadPoolExecutor.java:2086)
  at java.util.concurrent.ThreadPoolExecutor.reject (ThreadPoolExecutor.java:848)

  at com.google.firebase.crashlytics.internal.common.BackgroundPriorityRunnable.run (BackgroundPriorityRunnable.java:27)
  at java.lang.Thread.run (Thread.java:919)

Our first guess, since the stacktrace mentions the tasks package, was to force play-services-tasks:17.0.0. After doing this, we started seeing the following stacktrace (slightly different):

java.util.concurrent.RejectedExecutionException: 
  at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution (ThreadPoolExecutor.java:2086)
  at java.util.concurrent.ThreadPoolExecutor.reject (ThreadPoolExecutor.java:848)

  at java.lang.Thread.run (Thread.java:919)

Now, we also forced play-services-basement:17.0.0 and we're waiting to see if the crash is gone or not.
Will update here once we have further info.

mrwillis21 · 2020-10-27T16:25:59Z

@sergiomarqmoura Thanks so much! This is super helpful!

sergiomarqmoura · 2020-10-27T22:36:59Z

@mrwillis21 I can now confirm that forcing play-services-basement:17.0.0 still produces the last stacktrace in the message above, in some cases.
This is our current dependency tree for Crashlytics:

so in terms of Crashlytics dependencies we're still using different versions of, we have the following:

com.google.dagger:dagger:2.27 -> 2.29.1

Hi everyone.
We reproduced this crash on OPPO Reno V2 device. (It is only device where we can do it).
Steps to reproduce were following:

Start application
Rotate device (it lead to call configurationChanged)
Exit app

In log we saw the same crash stack.
java.util.concurrent.RejectedExecutionException: Task com.google.android.gms.tasks.zze@2a661c3 rejected from java.util.concurrent.ThreadPoolExecutor@2733a40[Shutting down, pool size = 1, active threads = 1, queued tasks = 0, completed tasks = 426] at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2086) at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:848) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1394) at java.util.concurrent.Executors$DelegatedExecutorService.execute(Executors.java:630) at com.google.android.gms.tasks.zzc.zza(com.google.android.gms:play-services-tasks@@17.1.0:6) at com.google.android.gms.tasks.zzq.zza(com.google.android.gms:play-services-tasks@@17.1.0:19) at com.google.android.gms.tasks.zzu.zza(com.google.android.gms:play-services-tasks@@17.1.0:104) at com.google.android.gms.tasks.zze.run(com.google.android.gms:play-services-tasks@@17.1.0:15) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641) at com.google.firebase.crashlytics.internal.common.ExecutorUtils$1$1.onRun(ExecutorUtils.java:60) at com.google.firebase.crashlytics.internal.common.BackgroundPriorityRunnable.run(BackgroundPriorityRunnable.java:27) at java.lang.Thread.run(Thread.java:919)

I tried to throw test exception during app exiting, but I had no luck.

P.S. Pseudo code for exit() method
currentActivity.finish(); currentActivity.onStop(); System.runFinalization(); System.exit(0);

mrwillis21 · 2020-10-29T15:56:47Z

@Filosov this is great! Thanks! Does this require the device rotation, or can you reproduce it without that step?

mrwillis21 · 2020-10-29T16:53:09Z

Also, @Filosov - since you're able to reproduce this, can you please run adb shell setprop log.tag.FirebaseCrashlytics DEBUG and then post the output of adb logcat -s FirebaseCrashlytics?

--------- beginning of crash`

I think device rotation is not mandatory, but it simplifier crash reproduce (because it generate non-fatal exception in my code). I guess that crash has occured because some of reporting task exists at the moment of app exiting (sending firebase event or sending non-fatal exception info).

This crash probably unrelated to screen rotation, my app has fixed screen orientation.

Hi everyone, an update from our side. We seem to have solved this with an update which essentially changed the following:

Downgraded firebase-analytics:17.6.0 -> 17.5.0
Downgraded firebase-messaging:20.3.0 -> 20.2.0
Removed an android:priority attribute from an intent filter registered in a BroadcastReceiver, since we thought this could affect the scheduling of Crashlytics tasks in some way.

We used to see this crash ~twice/hour and we've now been live for 3.5 days and not a single occurrence so far. However, we're not sure which of the actions did the trick

Mikhael-Danilov · 2020-11-02T23:52:21Z

I observed crashes with the following dependencies variants:

com.google.firebase:firebase-analytics:17.4.4
com.google.firebase:firebase-ads:19.3.0
com.google.firebase:firebase-crashlytics:17.1.1

com.google.firebase:firebase-analytics:17.5.0
com.google.firebase:firebase-ads:19.4.0
com.google.firebase:firebase-crashlytics:17.2.1

Crash rate ~ 3 crash per day

However, there is no new crash events since Oct 31 despite I haven't changed anything on my side.

Is crashlytics working for you?
