Exactly.

You pretty much got all my ideas around the problem right.

1) code generation

I simply don't like code generation. It makes setup of projects 
difficult. It easily breaks because of some wrong paths or forgotten 
re-generate. Has to integrate in IDEs.

2) special field classes

Using the normal classes is so much more natural. No need to convert.

3) Use values instead of always "new Integer(0)".

Yes this works. For almost all supported classes like: String, Integer, 
Long, LocalDate, LocalDateTime, LocalTime, BigDecimal.

For Boolean and Enum I would have to use the second solution.


I started with the framework with java 8. Never thought at that time 
this would become a problem.
