* One does not "simply"
* It's not obvious
* It's not really _that_ easily done
* Basically is basically a useless word
* Of course - if you already know how things work you wouldn't be reading the docs
* Clearly is maybe not so clear for everyone
* Just was just a bit harder as there are some uses that are just
* add java support in akka-actor module in the class Abstract.ActorContext by adding the setReceiveTimeout and CancelReceiveTimeout
* add akka.actor.AbstractActor#ActorContext cancelReceiveTimeout and setReceiveTimeout to mima-excludes file
* removed scala.concurrent.duration dependency in ActorDocTest and add new method expectTerminated with java.time.Duration support in TestKit
* used java.time.Duration as default import
* Add more convenient version of recover, recoverWith and recoverWithRetries for javadsl.Flow.
* The new method take a Class parameter to decide which failure to recover from.
* Also add corresponding unit tests for them.
* use case expression to express partial function
* make time out larger in unit test
* checkstyle
* fix parameter type
* Don't write to actual disk in test
* Silence expected log errors
* Bugfix #24924 UnfoldResource closed resource twice on failure
* One more case where close would be called twice
* Toggle closed flag after operation in restartState
* open false _before_ closing in restartState
* +str,typ introduce akka typed ask for akka stream
address feedback and add actor interop stages incl ask to docs
more compile tests and adjusted things
last docs
* document adding stages to docs in CONTRIBUTING
* address review comments
* rebase conflicts
`groupBy`'s default behavior is to filter elements, that would go to a substream
that is already closed. This allows `groupBy` to recreate those already closed streams,
if wanted, and run them as if they would've never run before in the first place.
Overload instead of default parameter
Make set of closed keys unmodifiable if not needed
Adjust documentation, adding a warning on memory consumption.
Add MiMa exclude.
