Description

Removing a parent object in OneToMany with cascade=CascadeType.ALL raises foreign key constraints exception

JpaParent.java
@OneToMany(mappedBy="parent", cascade=CascadeType.ALL)
private Set<JpaChild> children = new HashSet<JpaChild>();

JpaChild.java
@ManyToOne(optional=false)
@JoinColumn(name="ParentId", nullable=false)
private JpaParent parent = null;

// This raises the following exception. If foreign key is removed, it works OK (Maybe I have to let OpenJPA know about foreign key constraints)
JpaParent parent = em.find(JpaParent.class, 1);
em.remove(parent);
