In org.jboss.as.jpa.hibernate5.HibernatePersistenceProviderAdaptor.addProviderDependencies(PersistenceUnitMetadata pu), enable second level cache if persistence unit has hibernate.cache.use_query_cache or hibernate.cache.use_second_level_cache is true, then the second level cache should be enabled unless shared cache mode is set to NONE.

Workaround:

<shared-cache-mode>ALL</shared-cache-mode>

Or

<shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>
