so first question, do i need to start something like, ehcache or hibernate-jcache or hibernate-ehcache? i am very much interested in a KISS solution, just need to get this up and running for a 10 year old workflow app upgrading from hib 3, spring 2.5, tomcat 6 etc... ehcache from back in hib 3 works awesome for us. so i am just looking for no-harm upgrade motivated by hibernate 5.3 - that is what we need to change. so after much, much confusion about the easiest way to integrate hibernate 5.3 and ehcache, i decided on this: ivy.xml
