Persistence provider for Java that supports final fields

Question

I\'m very new to Java but I\'ve been developing a habit to use final wherever possible declaring immutability which i think is a good thing. (Consider f#)

I\'ve read

Answer 1

This may not be exactly what you're striving for, but the immutability principle can easily be supported by non-final private fields having only a getter. The compiler in fact recognizes this and generates code which is pretty much identical to what you'd get with fields declared as final.

This will require you to be conscientious and not change your fields from within the containing class (whereas final would enforce that), but I think this is not a big price to pay for the flexibility you gain.
