Xavi Arias updated OPENJPA-1891:
--------------------------------
Description:
The problem comes while enhancing entities at runtime by the Spring load time
weaver mechanism.
Spring load time weaver is configured with
"org.springframework.instrument.classloading.ReflectiveLoadTimeWeaver" and
Tomcat webapp class loader with
"org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader".
Everything works without any exception, but the enhancer does not find any
entity meta data. The log message for every entity is the following:
18:09:24,431 WARN openjpa.Enhance - Type "class model.Contact" has no
metadata; enhancing as persistence aware. If you intended for "class
model.Contact" to be persistence-capable, then this means that OpenJPA could
not find any metadata for "class model.Contact". This can happen if the
directory containing your metadata is not in your CLASSPATH, or if your
metadata files are not named properly. See the documentation on metadata
placement for more information.
After debugging, that the problem seems to come from the method
parseClassAnnotations in AnnotationPersistenceMetaDataParser. The call to
J2DoPriv5Helper.isAnnotationPresentAction(_cls, Entity.class) always return
false, while the class is actually annotated as an entity. This is because the
javax.persistence.Entity class passed as parameter is not the same as the one
in the entity class annotation map, so the subsequent call to
getAnnotation(Entity.class) always returns null.
