Michał Woś commented on ARIES-1341:
-----------------------------------
inside aries, JpaBeanProcessor
private Field getPersistenceField(Class<?> c) {
for (Field field : c.getDeclaredFields()) {
if (field.getAnnotation(PersistenceContext.class) != null) {
return field;
}
if (field.getAnnotation(PersistenceUnit.class) != null) {
return field;
}
}
return null;
}
field.getAnnotation(xxx) always returns null due to proxies
all issues are noticed in JpaBeanProcessor
> JpaBeanProcessor not working in karaf
