As per our JIRA discussion, this has been rolled into master in a slightly extended fashion, only applying setDefaultReadOnly(true) to transaction-local resources... which means no side effects for later access, and no cleanup neessary. Thanks for the PR, in any case!

@jhoeller was similar behaviour ever implemented for Hibernate 6?

Comment From: vladmihalcea

@jwgmeligmeyling Yes, the optimizations work just fine with Hibernate 6 because they are applied by the HibernateJpaDialect.

Check out this line in the HibernateJpaDialect for more details.
