runBlocking {
    val ceh = CoroutineExceptionHandler { _, throwable ->
        println("Failure with ${throwable.localizedMessage}")
    }
    val scope = CoroutineScope(SupervisorJob()+Dispatchers.IO+ceh)
    val j = scope.launch {
        val c1 = scope.launch {
            throw Exception("Exception1")
        }
        val c2 = scope.launch {
            delay(100)
            println("C2 still executing")
        }
        joinAll(c1, c2)
    }
    j.join()
}

Output:
Failure with Exception1
C2 still executing
Output if SupervisorJob isn't used:
Failure with Exception1
