* Copied from Lagom, with the following differences
* Jsonable and CompressedJsonable not included
* pcollection and guava modules not enabled by default
* added scala and afterburner modules
* JSON, CBOR and Smile options (different serializers)
* JMH benchmark
* jackson version 2.9.9
* test polymorphism
* serializer for ActorRef
* Address serializer
* FiniteDuration serializer, same as java.time.Duration
* use blacklist from Jackson databind against gadgets
* disallow binding to open ended types, such as java.io.Serializable
* Configurable ObjectMapper ser/deser features
* testing date formats with WRITE_DATES_AS_TIMESTAMPS on/off
* ActorSystemSetup for ObjectMapper creation
* and possibility to lookup created ObjectMapper via ObjectMapperProvider extension
* createObjectMapper without ActorSystem, needed by Lagom test
* add basic docs
* skip Scala 2.13 for akka-serialization-jackson for now, until the Jackson
Scala module has been released
* ClusterReceptionist using own ddata Replicator #26936
* otherwise application configuration, such as role may break it
* creating it as a child actor, path will be same on all nodes
* rolling update from 2.5 not supported
* mention in migration guide
* update migration note about receptionist rolling update
* Implements actorRef source variant with backpressure #17610
* Small improvements to documentation and source #17610
* Small improvements to test #17610
* Small improvements to implementation and tests #17610
* Adds API for akka-typed #17610
* Adds ack sender and java api for typed #17610
* simply ignore that compat test for 2.13 because the only reason for
testing Java serialization compat is that in Akka 2.4 it used
Java serialization (and in 2.5 when additional-serialization-bindings
was disabled)
* akka.build.version property, #26958
* and use timestamped snapshot version if "timestamp" is passed in
* to support publishing snapshots with same version for Scala 2.12 and 2.13
with +publish
* remove stampVersion plugin, since it's no longer needed
* store currentDateTime in system property
* to survive reloads
* This problem was introduced in the optimization in PR #26878,
and that regression has not been released.
* While waiting for the ddata update response it buffers messages
for the entity that is stopped/started and in the case of passivation
those buffered messages were not delivered afterwards. Therefore
the test failed when waiting for the expected response.
* While waiting for update to comple it will now deliver messages to other
already started entities immediately, instead of stashing
* Unstash one message at a time, instead of unstashAll
* Append messageBuffer for messages to the entity that we are waiting for,
instead of stashing
* Test to confirm the improvements
* Fixing a few other missing things
* receiveStartEntity should process the change before starting the entity
* lastMessageTimestamp should be touched from overridden deliverTo
* handle StoreFailure
* tried to investigate the (small) increase in LatencySpec that occured
when the internal-dispatcher was introduced
* couldn't see significant difference when running locally
* found a few more places where the internal-dispatcher should be used
* my thinking is that the additional latency could have been caused by
hopping between dispatchers, but I'm not sure if any of these
changes will have an effect (we'll see in Jenkins job)
* more clear router props
