Hi everyone,

I'm current facing an IllegalArgumentException related to
org.codehaus.backport175 (see below) during execution of my Akka Boot
class in an integration test. The error, however, appears to have no
impact on the test functionality?!
There's no problem when using untyped actors only...
I'm using Akka 1.0-M1, JUnit 4.5, and Specs 1.6.5

The exception trace is shown only once per Akka launch - during
creation of the first TypedActor (regardless of actor creation order).

My test setup may appear a bit odd, as I was trying to reproduce the
production setup.
The integration test launches a jetty instance with the WAR file (see
code below).
I haven't been able to reproduce the exception outside the integration
tests, so maybe this problem is related to how I start Akka/Jetty!?.

I'm happy about any hints and ideas.

Thanks!
-Tom


Test Code
------------------------------
trait JettySupport {
 protected val jettyServer = new Server(8080)
 protected val webappContext = new WebAppContext

 def startJetty = {
   webappContext.setContextPath("/")
   webappContext.setWar("integration/target/scala_2.8.0/web.war")
   jettyServer.setHandler(webappContext)
   jettyServer.start
 }

 def stopJetty = jettyServer.stop
}

class ChargerSimulatorRestEndpointTest extends Specification with
JettySupport {
 "Doing this" should {
   doBefore(startJetty)
   doAfter(stopJetty)
   "result in that" in {
     ...
   }
 }
}


Akka Boot
------------------------------
trait Hello

object HelloImpl {
 var count: Int = 1
}

class HelloImpl extends TypedActor with Hello with Logging {
 log info ("Hello " + HelloImpl.count)
 HelloImpl.count += 1
}

class Boot extends Logging with ConfigSupport {
 TypedActor.newInstance[Hello](classOf[Hello], classOf[HelloImpl],
5000)
 TypedActor.newInstance[Hello](classOf[Hello], classOf[HelloImpl],
5000)
 ...
}
