-------------------------------
> Constraint violation exception when removing relationship using

> Key: OPENJPA-2199
> URL: https://issues.apache.org/jira/browse/OPENJPA-2199
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.0.0, 2.1.0, 2.2.0, 2.3.0
> Reporter: Albert Lee
> Assignee: Albert Lee
> Fix For: 2.0.3, 2.1.2, 2.3.0, 2.2.1
>
>
> The problem occurs with the following relationships between classes:
> Parent ->* Child ->* GrandChild. Class Parent has a collection of Childs.
> Class Child has a collection of GrandChilds.
> Each one-to-many relationship is annotated like this: @OneToMany(cascade =
> CascadeType.
> ALL, orphanRemoval = true, ...). I.e. we use orphan removal and remove
> operations cascade from parents to children and grandchildren.
> When we do the following a DB constraint violation occurs:
> 1) Start a transaction
> 2) Load a Parent instance from the database
> 3) Navigate to a Child and modify it
> 4) Cut the relationship between Child and GrandChild
> 5) Cut the relationship between Parent and Child
> 6) Commit the transaction
> Caused by: org.apache.openjpa.lib.jdbc.ReportingSQLException: DELETE on table
> 'JPAORPHAN_CHILD' caused a violation of foreign key constraint
> 'SQL120320110237861' for key (11). The statement has been rolled back.
> {prepstmnt 1074806800 DELETE FROM APP.JPAORPHAN_CHILD WHERE ID = ?
