Create a PropsFactory that reuses the reflective constructor

To speed up things and consume less memory when creating actors with argument lists, we should create a PropsFactory that reuses the reflective constructor for a class and only validates the supplied arguments for each successive call.

Why do we store the constructor at all?

I'd love to avoid creating a caching problem

Also, this is also problematic:

private[this] def cachedActorClass: Class[_ <: Actor] = {
if (_cachedActorClass eq null)
cachedActorClass =
if (classOf[IndirectActorProducer].isAssignableFrom(clazz))
Reflect.instantiate(constructor, args).asInstanceOf[IndirectActorProducer].actorClass
else if (classOf[Actor].isAssignableFrom(clazz))
clazz.asInstanceOf[Class[ <: Actor]]
else
throw new IllegalArgumentException(s"unknown actor creator [$clazz]")

_cachedActorClass
}
