ReflectHelper.classForName() blocking in Hibernate

Solution Verified - Updated -

Issue

  • Code in ReflectHelper.classForName() may generate exceptions when attempting to load HQL tokens which are not classes
  • Blocking to create stack traces for ClassNotFoundException may impact performance in some cases:
    • In cases where entity manager factories or session factories are recreated frequently
    • In cases where there are thousands of distinct HQL queries

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP) 7
  • Hibernate 5
