For me the problem would be learning how something does or does not work, even with a compiled language. The reason I hate Spring for example (not that I've worked with it extensively) is that the documentation gives you zero feel for what you expect the behaviour to be. It will compile, but until you run it and check what it's doing, very often you'll be developing with no idea of what you're actually building. Especially if you're trying to get specific behaviour of what you want to see (e.g: figuring out why it won't send mail, or why it doesn't ignore a certain json key or whatever), it still needs many runs to get right.
