Hi Vaughn, Akka 2.4 is finally dropping java 6 support and requires java 8. It's more than just being compiled with 8, it actually uses types and APIs only available in 7+.
Java 6 has been end of lifed a very long time ago. Java 7 actually as well since April this year, except fixes for customers by Oracle, quote: "As outlined in the Oracle <http://www.oracle.com/technetwork/java/eol-135779.html#Java6-end-public-updates> JDK <http://www.oracle.com/technetwork/java/eol-135779.html#Java6-end-public-updates> Support Roadmap <http://www.oracle.com/technetwork/java/eol-135779.html#Java6-end-public-updates>, after April 2015, Oracle will not post further updates of Java SE 7 to its public download sites". So it really is time to update to 8 in projects. Akka's jump to Java 8 has been announced in December 2014, here: https://www.typesafe.com/blog/akka-roadmap-update-dec-2014 Akka 2.4 itself is binary compatible with Akka 2.3 though - when you use jdk8 - so you should be able to use the latest milestones with Play. We do offer builds of Akka that are jdk 6 compatible for customers though, if you really can not upgrade for some reason. It is additional work on our side and can not use some of the new features introduced in later jdk versions though. Hope this explains the decision and options available well. Depending on your needs I'd either simply upgrade to 8 if no very very very strong reason to stay on 6, or we'd need to talk about getting your customer a subscription and would need to make the new persistence included in the build (2.4-M... are basically development snapshots).
