I find this really interesting, and meets my (limited) Rails experience and (extensive) Java experience: I found it hard taking over an existing Rails project - it felt frail to me, that any small change might have unexpected consequences. Whereas when I've taken over Java projects - or come in late to an existing team - I felt quite confident getting started, even if it is a bit of a mess.
