But there are many (enterprise) applications there OOAD is not
suitable. Some OO languages (such as java) has disadvantages because
they don't allow first-order functions and function pointers.

If by "First order functions" you mean "blocks" or "Closures" then I'll happily agree with you. Anonymous inner classes are a poor substitute. If, on the other hand, you are just referring to regular global functions, then you are incorrect. One can very simple create them in Java by making them a static method of a class named Global.

As for function pointers, that's what OO is really all about. OO is a formalism that gives you function pointer capability without the "danger". Anything you can do with a function pointer in C, I can do with polymorphism in Java.
