[ https://issues.jboss.org/browse/WFLY-11991?page=com.atlassian.jira.plugin... ] Scott Marlow commented on WFLY-11991: ------------------------------------- If the Hibernate51TransformSessImplMtds system property is set to true, then all class methods definitions in the application will be transformed from using type org.hibernate.engine.spi.SessionImplementor to instead use type org.hibernate.engine.spi.SharedSessionContractImplementor. All method calls in the application will also be updated to switch from using type org.hibernate.engine.spi.SessionImplementor to instead use type org.hibernate.engine.spi.SharedSessionContractImplementor. These changes will cover the case where the application contains code that must be changed to use SharedSessionContractImplementor instead of SessionImplementor. The default for the Hibernate51TransformSessImplMtds system property is false (for backward compatibility) -- This message was sent by Atlassian Jira (v7.12.1#712002)
