Hi,

What dependencies are conflicting with recent postgres/postgis stores and what are actually the issues ?

I don't actually know... This is the only information that has been given to me. I could find out though, but I understand you agree with an upgrade in principle.

Anyway Hibernate 3.6.0.Final was release 7 years ago and has two major versions on top of it so upgrading to a more recent version is probably something that should be done:
https://mvnrepository.com/artifact/org.hibernate/hibernate-core

My main concern is the impact on existing installations of GeoFence, taking in account the commonly used databases (PostgreSQL, Oracle, ...) which versions will still compatible ? Hibernate rely on the JDBC driver of the database so the question can be rephrased, which JDBC versions are supported by 3.6.0.Final that are no supported by 5.x ?
From the hibernate website:

"Hibernate 5.2 and later versions require at least Java 1.8 and JDBC 4.2.

Hibernate 5.1 and older versions require at least Java 1.6 and JDBC 4.0."


I found posts via google that suggest hibernate 3.6 supported JDBC3, but I cannot find any official documentation that confirms this.


I think we could opt for hibernate 5.1 if that makes things more backwards compatible, because I was asked 5.x



The spatial extension of Hibernate also suffered several changes, do you see possible incompatibility issues ?

I cannot find documentation that lists migration issues. I am assuming I will face quite a few issues, but that these can be resolved. I am hoping that the test coverage is sufficient, so that if I can make all the tests work again I can assume that it works...

Regards
Niels
