This way of implementing a factory based on reflection is useful in a few special cases (like service provider frameworks - see effective java item#1) only, but in general we should avoid such implemenation for breaking compile time checks making an unverifiable dependancy of no arg consturctor in Actor implementations replacing ugly if-then-else conditional code with uglier reflection code making a new dependancy on a (compile time unverifable) configuration file (or even a mapping from string to class names in a source file)
