SessionFactory getImplementors method causes performance issues with entity-name attribute ------------------------------------------------------------------------------------------ Key: HHH-7286 URL: https://hibernate.onjira.com/browse/HHH-7286 Project: Hibernate ORM Issue Type: Improvement Components: core Affects Versions: 3.6.5 Environment: Hibernate 3.6.5 Final, Orcale database 11g, JBoss 4.2.2 Reporter: Alain Menu Hibernate provokes useless accesses to the class loader of JBoss due to the attribute entity-name which is present in each hbm mapping file. Hibernate tries to instantiate a class having this name before trying with the real name of the actual business object which cause a performance overhead and contention under heavy load conditions (benchmarking). <hibernate-mapping package="com.example.hibernate.businessobject"> <class name="Employee" table="EMP" entity-name="Employee_EMP"> <!-- cache usage="read-only"/ --> <id name="trigramme" type="string" column="CODUSR" /> <property name="firstname" column="PREUSR" type="string" /> <property name="name" column="NOMUSR" type="string" /> <property name="email" column="EMLUSR" type="string" /> </class> </hibernate-mapping> -- This message is automatically generated by JIRA.
