So I had a Spring 3.1.1.RELEASE/Hibernate 3.6.2.Final/Hibernate Validator 4.1.0.Final webapp that makes use of Joda DateTimes.
That version of h-v uses javax.valiation 1.0.0.GA.

There's a feature of javax.validation 1.1.0.Final I want to incorporate into my bean validation.
javax.validation 1.1.0.Final comes in with H5, so I've chosen to upgrade to H 5.0.3.Final

Question 1: what is the eariler major version of Spring that supports H5 ? I've seen posts where H5 works with S 4.2.2.RELEASE.
For now I've chose to upgrade to S 4.1.1.RELEASE

Various posts suggest using Jadira with H4. After struggling for a few days I turned up a post stating jadira usertypes is incompatible with H5

http://stackoverflow.com/questions/32448957/abstractmethoderror-in-sessionfactoryimpl-when-upgrading-to-hibernate-5

So that means skipping jadira and going back to Joda. But then I get runtime joda.nullSafeGet errors.

So, how does one get Joda DateTime fields annotated correctly with H5 without Jadira? Or failing that, can I drop back to H4x , bring in java.validation 1.1.0.Final as a dependency all its own then exclude that dependency within h-v 4.x ?

TIA

As of writing, this Spring issue is still open: https://github.com/spring-projects/spring-boot/issues/2763
There are also some workarounds for the naming strategy change.
Hibernate 5 features a hibernate-java8 dependency which allows you to use the Java 8 Date/Time classes.

I was able to get it work long outside the warnings mentioned above. There is now a 5.0 Jadira release that adds hibernate 5 support which is good for date but also for monetary amount support too before jdk9 official support.
