PersistenceProviderImpl.createContainerEntityManagerFactory() should not add a
ClassTransformerImpl to PersistenceUnitInfo if <exclude-unlisted-classes>
--------------------------------------------------------------------------------------------------------------------------------------------------------
Key: OPENJPA-72
URL: http://issues.apache.org/jira/browse/OPENJPA-72
Project: OpenJPA
Issue Type: Bug
Environment: JDK1.5, Win32, openjpa-0.9.0-incubating
Reporter: Corey Klaasmeyer
Adding a transformer is unnecessary if classes are enhanced at build time. As
far as I can tell, you specify this by adding the <exclude-unlisted-classes>
property to persistence.xml. This could probably be made more clear by calling
the property something like "build-time-enhancement-only" or
"disable-runtime-enhancement". Additionally, this causes a Spring configured
JPA to fail with and IllegalStateException if no LoadTimeWeaver is specified in
the LocalContainerEntityManagerFactory. The relevent code is on line 93 of
PersistenceProviderImpl
public EntityManagerFactory createContainerEntityManagerFactory(
PersistenceUnitInfo pui, Map m) {
PersistenceProductDerivation pd = new PersistenceProductDerivation();
try {
ConfigurationProvider cp = pd.load(pui, m);
if (cp == null)
return null;
// add enhancer
String ctOpts = (String) Configurations.getProperty
(CLASS_TRANSFORMER_OPTIONS, pui.getProperties());
pui.addTransformer(new ClassTransformerImpl(cp, ctOpts,
pui.getNewTempClassLoader()));
BrokerFactory factory = Bootstrap.newBrokerFactory(cp,
pui.getClassLoader());
return OpenJPAPersistence.toEntityManagerFactory(factory);
} catch (Exception e) {
throw PersistenceExceptions.toPersistenceException(e);
}
}
