[hibernate-issues] [Hibernate-JIRA] Resolved: (ANN-722) ANN-694 alive: FK circularity error under certain circumstances

ANN-694 alive: FK circularity error under certain circumstances --------------------------------------------------------------- Key: ANN-722 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-722 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.3.1.GA Environment: core 3.2.6, annotations 3.3.1.GA, entitymanager 3.3.2.GA, mysql 5 Reporter: Sven Woltmann Priority: Blocker Fix For: 3.3.2, 3.4.0.CR2 Attachments: CircularityTest2.rar The bug described in ANN-694 still exists in 3.3.1.GA under the following circumstances (see below for further description): ------------------------------------------------------------ @Entity public class A_PK implements Serializable { public D d; @ManyToOne public D getD() { return d; } public void setD(D d) { this.d = d; } } ------------------------------------------------------------ @Entity public class A implements Serializable { private A_PK id; @EmbeddedId public A_PK getId() { return id; } public void setId(A_PK id) { this.id = id; } } ------------------------------------------------------------ @Entity @Inheritance(strategy = InheritanceType.JOINED) public class B implements Serializable { @Id private int id; } ------------------------------------------------------------ @Entity public class C extends B implements Serializable { } ------------------------------------------------------------ public class D_PK implements Serializable { private C c; @ManyToOne public C getC() { return c; } public void setC(C c) { this.c = c; } } ------------------------------------------------------------ @Entity public class D implements Serializable { private D_PK id; @EmbeddedId public D_PK getId() { return id; } public void setId(D_PK id) { this.id = id; } } ------------------------------------------------------------ The references are as follows - there are no circularity dependencies: A --> A_PK --> D --> D_PK --> C --> B ------------------------------------------------------------ Hibernate throws the following exception: org.hibernate.AnnotationException: Foreign key circularity dependency involving the following tables: D, C, A at org.hibernate.cfg.AnnotationConfiguration.processFkSecondPassInOrder(AnnotationConfiguration.java:470) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:304) at org.hibernate.cfg.Configuration.generateDropSchemaScript(Configuration.java:762) at org.hibernate.tool.hbm2ddl.SchemaExport.<init>(SchemaExport.java:93) at org.hibernate.tool.hbm2ddl.SchemaExport.<init>(SchemaExport.java:61) at test.DoTest.initTest(DoTest.java:22) ------------------------------------------------------------ When I do any of the following, *no* exception is thrown: - class A_PK: reference "C" instead of "D" (removing "C" from the dependency chain) - class A: move annotation from getter to field declaration "private A_PK id" - class A: replace embedded id "A_PK" by reference to "D" (as in "A_PK") - class A: rename class to "Z" - class B: remove "strategy" parameter from "@Inheritance" annotation - class C: not extending "B" and defining the primary key in "C" - class C: rename class to "Z" - class D: move annotation from getter to field declaration "private D_PK id" - class D: replace embedded id "D_PK" by reference to "C" (as in "D_PK") Attached you'll find a test case.
