Is it safe to use AtomicLong inside coroutines? I have the following code:

fun a() {
    Log.i("Log info")
        launch {
            myAtomicLong.set(SystemClock.elapsedRealtime()) 
            Log.i("Log info in launch")
        }
}

The second Log.i never gets executed. It’s inside a class implementing coroutineScope on Dispatchers.IO. The AtomicLong is used in multiple of those launch blocks.

Maybe scope is alrady cancelled? Does it execute if you comment out atomic call?

as safe as in Java, Kotlin coroutines do not impose more restrictions to Java threads

I think you are correct about the cancelled scope, the job has a parent that might call cancelChildren() which then would make all the launches useless (🤦‍♂️ <- me)
