@mraible We should consider to migrate from zalando (problem and problem-spring-web) to spring-framework native implementation coming with spring-framework 6.0

@pascalgrimaud same for JHLite

Thanks for the information @DanielFran !

I'm looking for issues to try and fix at the JavaOne Hackergarten, so this could be a candidate.

Does anyone know how to fix the compilation errors from Hibernate? Do we still need the fixed PostgreSQL dialects in jhipster-framework?

@mraible The fixed PostgreSQL dialect was needed for BLOB integration: https://github.com/jhipster/jhipster-bom/blob/main/jhipster-framework/src/main/java/tech/jhipster/domain/util/FixedPostgreSQL10Dialect.java#L37-L39

We just need to confirm hibernate 6 handles it now: https://docs.jboss.org/hibernate/orm/6.1/userguide/html_single/Hibernate_User_Guide.html#basic-blob
