Are all compile-time constants inlined?

Question

Let\'s say I have a class like this:

class ApplicationDefs{
public static final String configOption1 = \"some option\";
public static final String configOpti         


        

Answer 1

There is nothing here that says these values should be inlined. You are just declaring some public, static members. Those other classes are using the values of these members. No inlining is asked. Even the final keyword

But for performance reasons, some JVMs may inline these values in those other classes. This is an optimization. No optimization should change the behaviour of a program. So if you change the definition of these members, the JVM should un-inline the previous values.

This is why there is no way to turn inlining off. Either the JVM does not inline and there is no problem or if it is inlined, the JVM guarantee the un-inlining.

I am not sure what happens when you import statically this class. I think (not sure) the inlining is performed and may cause the trouble you mention. If that is the case, you could basically delete the static import and you are ok.
