I did some work off-camera to make the actors and message queues type parameterized, so that a similar bug as was in episode 25 would not happen ever again. In the beginning of this episode I will explain what I did and what kinds of Java generics tricks I was able to use to minimize the boilerplate in the Guice modules. Then it's time to write unit tests for things which are covered only by end-to-end tests.
