Stale data found in Infinispan cache following Hibernate JPAQL UPDATE or DELETE in JBoss EAP

Issue

• A JPAQL operation is used to modify data in the database (e.g. entityManager.createQuery("update Employee e set e.title = 'Senior Engineer'").executeUpdate();)
• The Infinispan cache region seems to be immediately purged
• Any subsequent load of the relevant entities (from another thread) loads data into the cache which will be stale as soon as the database commit for the updating thread completes.
• No invalidation of the cache region occurs following the database commit.
  • This is a change in behavior compared to EAP 7.1 / Hibernate 5.1 / Infinispan 8.2
