Not sure about this, as a final value should be in-lined regardless of
how it is initialized. But this can be tested, I suppose.
I mean a final field in class A can only be in-lined in class B at
compile (java source to byte-code) time if the compiler can determine
its value. I think this is only currently true if the field is a literal
(or set to another final field that is sourced from a literal). If the
final value comes from file through a method call then the compile will
not be able to in-line it.
At runtime the jit can probably in-line, but that's not what I meant.
