EventFilter does not work as expected

[Aaronontheweb]

I ran into some trouble with the EventFilter - we are trying to use it in our implementation of BarrierSpec in the multi-node TestKit: https://github.com/akka/akka/blob/master/akka-remote-tests/src/test/scala/akka/remote/testconductor/BarrierSpec.scala#L43

1. The old EventFilter methods on AkkaSpec hide the EventFilter property on TestKit, so it's not easily accessible at the moment.
2. Do any of the new EventFilter overloads support something as simple as what BarrierSpec is trying to accomplish here? https://github.com/akka/akka/blob/master/akka-remote-tests/src/test/scala/akka/remote/testconductor/BarrierSpec.scala#L43 - seems like the new methods want a lot more filtering on the objects themselves. The old EventFilter methods don't work either because they're re-using the TestActor for all of the filter messages and the internal ExpectMsg<Error> call will fail if the TestActor receives a message before the event is logged to the filter.

1 Yep, we need to fix #377
2 This code in scala

  EventFilter[BarrierEmpty](occurrences = 1) intercept {
         ...
      }

is in c#

EventFilter.Exception<BarrierEmpty>().ExpectOne(() =>
{
  ...
});

Cool, just tried this inside the Remote TestKit!

Ok to close?

yep, working fine IMHO
