Static typing saved him from bugs, no doubt. But reread his post, especially...

For the first time, I consciouly took note of how much time I spent converting types, e.g., the number 100, some wants it to be long, some String, some Long, and then the dreaded "List/Vector of Long" to long[], or Long[].

I don't know whether to blame the authors of his framework for this sad state of affairs, or if Java itself should take the blame for enabling such hideousness. Surely, you're not going to defend those piss poor APIs, right?
