I verified now that there are zero org.hibernate.internal.SessionFactoryImpl instances in memory. I'll try again with "/standalone.sh" on WildFly 13, which will use Hibernate ORM 5.1 instead. was (Author: smarlow): I started up WildFly 13, with Hibernate 5.3.1.Final and couldn't reproduce with the following steps: # Copied HibernateLeakTest-1.0-SNAPSHOT.jar into wildfly/standalone/deployments and then started up WildFly using "/standalone.sh -Dee8.preview.mode=true" # I touched (updated) the wildfly/standalone/deployments/HibernateLeakTest-1.0-SNAPSHOT.jar four times, which caused it to redeploy four times, no leak (I only see one instance of org.hibernate.internal.SessionFactoryImpl instances in memory). # I removed the wildfly/standalone/deployments/HibernateLeakTest-1.0-SNAPSHOT.jar file, which undeployed it.
