Applications that extend certain Hibernate classes should be updated to use type SharedSessionContractImplementor instead of SessionImplementor ----------------------------------------------------------------------------------------------------------------------------------------------- Key: WFLY-11991 URL: https://issues.jboss.org/browse/WFLY-11991 Project: WildFly Issue Type: Bug Components: JPA / Hibernate Reporter: Scott Marlow Assignee: Scott Marlow Priority: Major Fix For: 17.0.0.Final Attachments: afterchange.zip, beforechange.zip The idea is to transform any class method parameter of type org.hibernate.engine.spi.SessionImplementor, in user application, to instead use type org.hibernate.engine.spi.SharedSessionContractImplementor. The test case (change) is for this enhancement is [https://github.com/simkam/wildfly/compare/hibernate_transformer]. The test case change is adding an internalNullSafeGet method that should also be transformed to use the SharedSessionContractImplementor type but was not, which led to an application failure with code: {code} public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor session, Object owner) throws HibernateException, SQLException { return internalNullSafeGet(rs, names, session, owner); } private Object internalNullSafeGet(ResultSet rs, String[] names, SessionImplementor session, Object owner) throws HibernateException, SQLException { internalSessionImplementorUsingMethod(session); session.isTransactionInProgress(); int result = rs.getInt( names[0] ); if ( rs.wasNull() ) return null; return State.values()[result]; } } {code}
