Adobe CQ / AEM akka integration

Question

I was playing around adobe cq and scala and as a result I was able to write scala service and deploy it to osgi container.

Afterwards I tried to integrate akka with following tutorial and I get the following error

28.08.2014 12:23:45.656 *ERROR* [0:0:0:0:0:0:0:1 [1409217825642] POST /system/console/bundles/352 HTTP/1.1] cqse-httpservice %bundles.pluginTitle: Cannot start (org.osgi.framework.BundleException: Activator start error in bundle com.aem.twitter-aem [352].) org.osgi.framework.BundleException: Activator start error in bundle com.aem.twitter-aem [352].

It throws NoClassDefFoundError, but I can see that class in Scheduler.scala file

Sometimes a class is already part of the osgi framework bundle but not exported/visible. You could try to add the package which causes problems to the "org.osgi.framework.bootdelegation" in the "sling.properties" — Thomas, Aug 28 '14 at 10:31

If adding sun.misc to org.osgi.framework.bootdelegation in sling.properties did not work for you, try adding the following OSGI fragment artifact as a dependency:

<dependency>
    <groupId>com.github.livesense</groupId>
    <artifactId>org.liveSense.fragment.sun.misc</artifactId>
    <version>1.0.5</version>
</dependency>

This bundle extends the System Bundle export list with the sun.misc package such that OSGi bundles may refer to Sun's misc implementation without the OSGi framework itself to provide it in a non-portable way.

http://mvnrepository.com/artifact/com.github.livesense/org.liveSense.fragment.sun.misc

In other words, the fragment attaches to the System Bundle and modifies the exports, such that sun.misc packages are exposed for import by other bundles. By default, the framework bundle only exports the java.* and javax.* packages. The sun.misc packages are necessary for certain dynamic and low-level language features in Groovy/Scala/Akka.
