- it’s a completely new-written thing in pure Java, so that “protected”
modifiers actually work and no ghost errors appear wrt. inheriting
from PartialFunction or similar
- it also features integration with the EventFilter
- all closure-based constructs are modeled as inner classes of the
JavaTestKit, where the user needs to override a single method which
will then be executed
- include move of doc samples out of akka package also in the
includecode directives
- fix broken serialization docs, which require one thing in the akka
package
