My app restarted itself, log shows ChimeraModuleLdr: Module config changed, forcing restart due to module

Question

I was testing my app and I saw it restart itself, was really weird. I looked and looked on the logs and I couldn't find anything odd except for this line ChimeraModuleLdr: Module config changed, forcing restart due to module. This is on a Pixel XL with Oreo.

Here are the last few lines of the log and the start up of the app after it was killed.

10-18 22:49:31.262  8379  8379 I ChimeraModuleLdr: Module config changed, forcing restart due to module 
10-18 22:49:31.262  8379  8379 I Process : Sending signal. PID: 8379 SIG: 9
--------- beginning of main

10-18 22:49:31.641 13717 13717 I MultiDex: VM has multidex support, MultiDex support library is disabled.

Any idea about what triggered this?

It seems that the ChimeraModule (or Dynamite) is the dynamic module loading system used by the Google Play Services (more details here).

I guess that, if your app is using a specific module from the Google Play Services, when that specific module is updated your app is restarted as well.
