@PrimaryKeyJoinColumn(...) is not working equivalently to @JoinColumn(..., insertable = false, updatable = false) ----------------------------------------------------------------------------------------------------------------- Key: HHH-5741 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5741 Project: Hibernate Core Issue Type: Bug Components: annotations, core, entity-manager, metamodel Affects Versions: 3.6.0 Environment: Hibernate Core 3.6, HSQLDB, JavaSE, Ant Reporter: Karsten Wutzke Priority: Critical When annotating classes with @JoinColumn(..., insertable = false, updatable = false) validation is working as expected: @ManyToOne @JoinColumns(value = {@JoinColumn(name = "country_code", referencedColumnName = "country_code", insertable = false, updatable = false), @JoinColumn(name = "state_code", referencedColumnName = "state_code", insertable = false, updatable = false), @JoinColumn(name = "city_name", referencedColumnName = "name", insertable = false, updatable = false)}) private City city = null; When annotating with the equivalent @PrimaryKeyJoinColumn, e.g.: @ManyToOne @PrimaryKeyJoinColumns(value = {@PrimaryKeyJoinColumn(name = "country_code", referencedColumnName = "country_code"), @PrimaryKeyJoinColumn(name = "state_code", referencedColumnName = "state_code"), @PrimaryKeyJoinColumn(name = "city_name", referencedColumnName = "name")}) private City city = null; ... validation fails. As every child knows (*cough*) @PrimaryKeyJoinColumn(...) is equivalent to @JoinColumn(..., insertable = false, updatable = false).

I have attached two SSCCE programs using JavaSE, HSQLDB, and Ant. The one uses @JoinColumn and works, whereas the other uses @PrimaryKeyJoinColumn and doesn't work.
