Hi,

Further to my previous post - Dali helped clear a few issues, but unfortunately the problems still persist =( (intentional bad pun)

When weaving is set to false the unit tests run fine, but in Equinox I still see:

Exception [EclipseLink-30005] (Eclipse Persistence Services - 2.1.0.v20100311-r6779): org.eclipse.persistence.exceptions.PersistenceUnitLoadingException

Caused by: javax.persistence.PersistenceException: Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.1.0.v20100311-r6779): org.eclipse.persistence.exceptions.EntityManagerSetupException

The order of exceptions changes with each run, but is always reported on a many-to-many relationship, the mapping of this one is specified as:

@OrderBy("date")

@ManyToMany(fetch = FetchType.LAZY, targetEntity = Interaction.class)

@JoinTable(name = "interaction_person", joinColumns = { @JoinColumn(name = "people") }, inverseJoinColumns = { @JoinColumn(name = "interactions") } )

private List<Interaction> interactions;

and on another (exception is identical apart from class references):

@ManyToMany(targetEntity = OutlookInvitationEmail.class, fetch = FetchType.LAZY)

@JoinTable(name = "staff_invitations", joinColumns = { @JoinColumn(name = "recipients") },

inverseJoinColumns = { @JoinColumn(name = "invitations") } )

private List<OutlookInvitationEmail> invitations;

With weaving set to dynamic, for Unit tests, I get:

So looking at ForeignReferenceMapping.java:852 I set weaving.lazy set to false and instead got:
