Maybe. I've seen few Java apps that don't use Spring or something similar. The parent described a simple domain, arguing it is the common case, but nonfunctional requirements like testing typically make the problem more complex. So I dispute that Java is good enough for the common case and that nothing from Haskell would be beneficial. Incidentally, Java's leadership agrees.
