Parent-child self-referencing relationship via link table causes QuerySyntaxException:(table) is not mapped when retrieving previous revisions

Description

We have a parent-child relationship set up for an entity using a plain link table. This is annotated with @JoinTable and @AuditJoinTable so there is no entity for the link table itself. The definition looks something like this...

@Entity
@Table(name = "BKG_BKCM_BKG_CMPT")
@Audited
public class BookingComponent implements Serializable {

@ManyToOne(fetch = FetchType.LAZY, optional = true)
@AuditJoinTable(name = "BKG_BKCMR_REL_AUD", inverseJoinColumns = { @JoinColumn(name = "BKCM_ID_PARENT", nullable = true, updatable = false) })
@JoinTable(name = "BKG_BKCMR_REL", joinColumns = { @JoinColumn(name = "BKCM_ID_CHILD", nullable = true, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "BKCM_ID_PARENT", nullable = true, updatable = false) })

private BookingComponent parent;

@OneToMany(mappedBy = "parent")
private List<BookingComponent> children;
}

We've found two issues. Firstly, when we try to retrieve a previous revision of these entities (they in turn are held in a collection in a container entity) using List<>.size() Envers seems to be constructing a JPQL query using the link table's table name which isn't valid JPQL resulting in the following exception:

org.hibernate.hql.ast.QuerySyntaxException: BKG_BKCMR_REL_AUD is not mapped [select new list(ee, e) from BKG_BKCMR_REL_AUD ee, package-name-omitted.BookingComponent_AUD e where ee.originalId.BookingComponent_id = e.originalId.id and ee.originalId.children_id = :children_id and e.originalId.rev_id.id <= :revision and ee.originalId.rev_id.id <= :revision and ee.rev_type != :delrevisiontype and e.rev_type != :delrevisiontype and (e.REV_ID_END.id > :revision or e.REV_ID_END is null) and (ee.REV_ID_END.id > :revision or ee.REV_ID_END is null)]

We've also noticed that the audit entries for the link table have a null REV_ID_END despite there being multiple revisions.

See attached gjkrupa_envers_problem.zip for a test case that demonstrates this issue.
