    text
    copied!<p>Given the following code:</p> <pre><code>import akka.actor._ object TraitTest { trait A { def something() } trait B extends A class C extends TypedActor with B { override def something() { println("Why am I not implemented?") } } def main(args: Array[String]) { val service = TypedActor.newInstance(classOf[B], classOf[C]) service.something() } } </code></pre> <p>When running the <code>main</code>, I get the following exception:</p> <pre><code>Exception in thread "main" java.lang.AbstractMethodError: TraitTest$B$$ProxiedByAWDelegation$$1322144340710.something()V at TraitTest$.main(TraitTest.scala:29) at TraitTest.main(TraitTest.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) </code></pre> <p>Now, google finally spat out <a href="https://www.assembla.com/spaces/akka/tickets/552-abstractmethoderror-when-invoking-method-not-in-interface-for-typedactor" rel="nofollow">this</a> link, however I don't understand how this 'works as designed'.</p> <p>Could anybody please shed some light on the issue?</p> <p>Thanks! </p> <p><strong>Edit</strong><br/> If I change my code as follows, I obviously do not get the error. However, this is of course not a solution, but more a temporary workaround.</p> <pre><code>trait B extends A { override def something() } </code></pre>
