As of Spring Framework 5.0, let's upgrade to the latest feasible baseline for EhCache 2.x, next to supporting the then-available EhCache 3.0 GA.

+1 for EhCache 2.7

The EhCache 2.7+ upgrade is unfortunately troubled due to Hibernate 4.x and even 5.0 not working with EhCache 2.7+ for Hibernate's own second-level cache adapter. See https://jsoftbiz.wordpress.com/2013/03/14/hibernate-4-and-ehcache-higher-than-2-4-3/ and the linked Hibernate issue for a discussion around that sad fact which the Hibernate team doesn't really seem to care about. We might see modern-day EhCache support in Hibernate 5.1, but even that part is not a done deal yet.

Since we're definitely going JPA 2.1+ in Spring 5 now, we could go Hibernate 4.3+ at the same time... possibly even 5.0+... not sure about 5.1+ though :-(

As per #18400, we intend to drop Hibernate 4.x support in Spring 5. EhCache 2.10 support is now definitely in Hibernate 5.1, so we should be covered there. Formally, we are going to require Hibernate 5.0+ in Spring 5, but effectively everybody is going to use Hibernate 5.1+ anyway.

Reducing this issue to the EhCache baseline only, since there is no technical driver for going beyond Jackson 2.6+ yet...
