It depends a little bit about what you are doing.

I would not want to implement a Java EE 6 server without being
allowed to use reflection.

Even some business code can use some reflection even though in
most cases it is better to hide the reflection via some DI
framework.

Reflection is a very useful tool and a very powerful tool. One
should just limit its use to where it is necesarry.

A B-52 bomber is also pretty powerful if you want to engage in a war.
It is not the correct tool for getting rid of the mosquitos in the
house.
