Uncaught error from default dispatcher causes fatal error with JavaTestKit

Question

I\'m just getting my feet wet with Akka. I\'m trying to write a JUNit test using the JavaTestKit from this Maven dependency:

    
        &         


        

Answer 1

I figured out the issue. It had to do with an incompatible combination of the Akka and Testkit libraries (Scala 2.10 vs 2.11). The following Maven dependencies worked as expected:

    <dependency>
        <groupId>com.typesafe.akka</groupId>
        <artifactId>akka-actor_2.10</artifactId>
        <version>2.3.12</version>
    </dependency>
    <dependency>
        <groupId>com.typesafe.akka</groupId>
        <artifactId>akka-testkit_2.10</artifactId>
        <version>2.3.12</version>
    </dependency>
    <dependency>
        <groupId>org.scala-lang</groupId>
        <artifactId>scala-library</artifactId>
        <version>2.10.5</version>
    </dependency>
