Found-shared-references-to-a-collection

Hibernate ORM

In one of my entity I did map using referencedColumnName as below before it was working
after upgrading hibernate search 5.8.0.Final getting error for translations:

@Column(name=“task_outcome”, length=64, updatable=false)
private String outcome;

@OneToMany
@JoinColumn(name=" key ", referencedColumnName=“task_outcome”, insertable=false, updatable=false)
private Set translations;

ERROR ::
Found shared references to a collection: com.eurodyn.eips.core.db.entity.HistoryTask.translations; nested exception is org.hibernate.HibernateException: Found shared references to a collection: .core.db.entity.HistoryTask.

My configuration as below :

<hibernate.entitymanager-version>5.2.11.Final</hibernate.entitymanager-version>
<hibernate.search-version>5.8.0.Final</hibernate.search-version>

The problem with “shared references” is that you seem to have multiple associations that map to the same join table through the same key. In such a scenario, Hibernate is unable to determine the source it should use for synchronizing to that join table for that key. I guess that since “outcome” is not unique and you loaded two entities referring to the same outcome you run into such a situation. You will have to add a unique constraint for the task_outcome column.
