I have java web project in eclipse Luna. The compiler level is "1.6".
I need some 1.7 functionality so I change the level to "1.7" and the java code in the project. There's no compile error.
Now, I'm going to deploy my code. My question is;
Is it safe to deploy only changed class to production? Or do I have to deploy all classes?
PS: production server JRE level is 1.7 already.
Regards.
