Hi!
I'm using EclipseLink 2.0.1 together with Spring's -javaagent:org.springframework.instrument-3.0.2.RELEASE.jar. Now I added my first MappedSuperclass to my model and there seems to be an issue with dynamic weaving not really weaving that MappedSuperclass.
Facts:
* No problem if using static weaving
* My mapped superclass is never passed to Spring's InstrumentationLoadTimeWeaver, so Eclipselink actually doesn't get a chance to weave its stuff in
Example:
@MappedSuperclass
public abstract class AbstractAuditableEntity {
...
}
@Entity
public class LocalizedMessage extends AbstractAuditableEntity {
...
}
As soon as I execute a query and Eclipselink tries to create an instance of LocalizedMessage I get an exception like this which tells me that weaving didn't ocurr:
Caused by: java.lang.NoSuchMethodError: com.beeline.bop.common.model.AbstractAuditableEntity.<init> (Lorg/eclipse/persistence/internal/descriptors/PersistenceOb ject;)V

So, I don't know if this is an EclipseLink bug, a Spring bug or a bug when using a combination of both. Does anybody have any ideas?
Maybe a classloading problem and EclipseLink should make sure all classes in persistence.xml are actually loaded after persistence context initialization?

Sounds like it could be a bug in Spring, it might not be considering @MappedSuperclasses for weaving. You might try logging a bug on Spring, and use static weaving as a workaround.
Note, that Spring also has a weaving issue that it does not allow instrumentation until the Spring context is accessed by your application. If you application has trigger the loading of any of the classes before this, then they will already be loaded and will not get weaved.
