Hi Jason, sadly the sbt-osgi plugin did something rather silly (I went in and fixed the plugin today) breaking the release if Java Marshallers are used. See here for details and workaround: https://github.com/akka/akka/issues/21105
Thanks for trying out the release candidate and thanks for your understanding - sorry that it's dead-on-arrival. A stable 2.4.9 is coming any day now – that will work then. We did a ReleaseCandidate this time as we weren't sure about some changes, glad we did an RC because indeed one of them turned out to be a problem. -- Konrad 'ktoso’ Malawski Akka <http://akka.io> @ Lightbend <http://lightbend.com> <http://java.pl/>java.pl / geecon.org / krakowscala.pl / lambdakrk.pl / sckrk.com On 4 August 2016 at 00:17:30, Jason B (jason.boutw...@gmail.com) wrote: Got this error after upgrading Akka versions in sbt build file from 2.4.8 to 2.4.9-RC1, and attempting to integrate JSON Streaming functionality.
