ClassNotFoundException: org.hibernate.cache.ehcache.internal.SingletonEhCacheRegionFactory

[Ashwini Jadhav]

Hi,

While migrating our application from JBoss EAP 6.4 to WildFly 18, we have migrated hibernate from 4.2.18 to 5.3.14.

So currently we are using hibernate-ehcache-5.3.14.Final.

Earlier we were using org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory which as per below thread is moved to org.hibernate.cache.ehcache.internal.SingletonEhCacheRegionFactory.

But when we try to use org.hibernate.cache.ehcache.internal.SingletonEhCacheRegionFactory, we are getting below error while deployment.
