is it possible with

joinAll

that it throws

CancellationException

when this occurred in any of the

launch {}

?

I’m not sure about what you’re asking, but a

Job

started inside a

Job

will cause its parent to fail if it fails. Take a look at

SupervisorJob

. Note that a

Job

throwing a

CancellationException

would not cancel its parent

Job

I assumed the

CancellationException

would also cancel the parent.
