[hibernate-issues] [Hibernate-JIRA] Resolved: (HV-562) Incorrect use of TCL to check visibility to JPA classes

Incorrect use of TCL to check visibility to JPA classes ------------------------------------------------------- Key: HV-562 URL: https://hibernate.onjira.com/browse/HV-562 Project: Hibernate Validator Issue Type: Bug Components: engine Affects Versions: 4.1.0.Final Reporter: Sanjeeb Sahoo Priority: Critical _org.hibernate.validator.engine.resolver.DefaultTraversableResolver_ uses Thread's context class loader to check existence of _PERSISTENCE_UTIL_CLASS_NAME_ as shown in the code below: The following code: {code} private void detectJPA() { try { loadClass( PERSISTENCE_UTIL_CLASS_NAME, this.getClass() ); log.debug( "Found {} on classpath.", PERSISTENCE_UTIL_CLASS_NAME ); } {code} _loadClass()_ first tries to use TCL to load the class. If TCL can't load, then it uses the class loader of the second argument to load the class. This is incorrect. It does not matter whether TCL can load _PERSISTENCE_UTIL_CLASS_NAME_, what matters is whether the class loader which is going to be used to load _JPA_AWARE_TRAVERSABLE_RESOLVER_CLASS_NAME_ can load _PERSISTENCE_UTIL_CLASS_NAME_ or not. Since HV-363 has now been fixed to use current class loader to load _JPA_AWARE_TRAVERSABLE_RESOLVER_CLASS_NAME_, the same class loader should also be used to detect existence of _PERSISTENCE_UTIL_CLASS_NAME_.
