PR for master (ORM 5.4) is here: https://github.com/hibernate/hibernate-orm/pull/2494/files
This patch is a followup of some background work Sanne is doing on Hibernate. It is an improvement, not a bugfix. It can significantly reduce the memory usage of Hibernate by interning highly redundant strings.
Sanne told me Jason Greene wanted this one in EAP. Jason, could you confirm?
Martin Simka I think we will need QE's blessing on this one too.
