HV uses Thread's context class loader to load internal implementation classes
-----------------------------------------------------------------------------
Key: HV-363
URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-363
Project: Hibernate Validator
Issue Type: Bug
Components: engine
Reporter: Sanjeeb Sahoo
Assignee: Hardy Ferentschik
Priority: Blocker
org.hibernate.validator.engine.resolver.DefaultTraversableResolver uses Thread's
context class loader to load JPA_AWARE_TRAVERSABLE_RESOLVER_CLASS_NAME, which is
org.hibernate.validator.engine.resolver.JPATraversableResolver. Why? Since one
implementation class is looking for another implementation class, should it not use
getClass().getClassLoader() instead? The relevant code is given below:
private void detectJPA() {
try {
loadClass( PERSISTENCE_UTIL_CLASS_NAME, this.getClass() );
log.debug( "Found {} on classpath.", PERSISTENCE_UTIL_CLASS_NAME );
}
catch ( ValidationException e ) {
log.debug(
"Cannot find {} on classpath. All properties will per default be
traversable.",
PERSISTENCE_UTIL_CLASS_NAME
);
return;
}
try {
@SuppressWarnings( "unchecked" )
Class<? extends TraversableResolver> jpaAwareResolverClass = (Class<? extends
TraversableResolver>)
loadClass(JPA_AWARE_TRAVERSABLE_RESOLVER_CLASS_NAME, this.getClass() );
NewInstance<? extends TraversableResolver> newInstance = NewInstance.action(
jpaAwareResolverClass, "" );
if ( System.getSecurityManager() != null ) {
jpaTraversableResolver = AccessController.doPrivileged( newInstance );
}
else {
jpaTraversableResolver = newInstance.run();
}
log.info(
"Instantiated an instance of {}.",
JPA_AWARE_TRAVERSABLE_RESOLVER_CLASS_NAME
);
}
catch ( ValidationException e ) {
log.info(
"Unable to load or instanciate JPA aware resolver {}. All properties will per
default be traversable.",
JPA_AWARE_TRAVERSABLE_RESOLVER_CLASS_NAME
);
}
}
