Mystery java.lang.RuntimeException: at android.os.PowerManager$WakeLock.acquireLocked (PowerManager.java:2212)

Question

App has been running in production for many years suddenly decided to throw a onetime RuntimeException.

This was reported by the Play Console crash tracking page. About all I know about it is that it happend on a Galaxy S7 running Android 8.0

The complete stack trace is

java.lang.RuntimeException: 
  at android.app.ActivityThread.handleReceiver (ActivityThread.java:3399)
  at android.app.ActivityThread.-wrap18 (Unknown Source)

There most likely was a nice descriptive message included in the thrown exception, but unfortunately the exception message is not and never has been included in Play Console Crash reports.

If I knew how to find the source code for this particular version of the PowerManager class, I could look it up there. But alas, that has also proven to be beyond my capabilities.

Any help or suggestions would be gratefully appreciated.

Thanks
