The subject pretty much says it all. I have the following in my pom:

<!-- akka -->
<dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-actor_${scala.binary.version}</artifactId>
    <version>2.3.9</version>
</dependency>

<dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-slf4j_${scala.binary.version}</artifactId>
    <version>2.3.12</version>
</dependency>

<dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-stream-experimental_${scala.binary.version}</artifactId>
    <version>1.0</version>
</dependency>

<dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-http-experimental_${scala.binary.version}</artifactId>
    <version>1.0</version>
</dependency>

<dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-http-core-experimental_${scala.binary.version}</artifactId>
    <version>1.0</version>
</dependency>

<dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-http-spray-json-experimental_${scala.binary.version}</artifactId>
    <version>1.0</version>
</dependency>

I have a lot of dependencies, but I'm pretty sure I've excluded things such that no other version of akka is being brought in (per mvn dependency:tree).

Seems you're mixing up dependencies.

Please don't use 2.3.9, use 2.3.12 (see your akka-actor dependency).
