Error description
EclipseLink performs an INSERT followed by an UPDATE when persisting a unidirectional OneToMany mapping. However, if the mapping is not nullable, EclipseLink attempts to INSERT a null value, causing a SQLIntegrityConstraintViolationException.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty - Java Persistence APA - * * JPA 2.1 & EclipseLink * **************************************************************** * PROBLEM DESCRIPTION: EclipseLink attempts to INSERT NULL * * values for Unidirectional @OneToMany * * relationships that are * * 'nullable=false' * **************************************************************** * RECOMMENDATION: * **************************************************************** Example: @Entity @Table(name="COMMENT") public class Comment { @Id @Column(name="COMMENT_PK", nullable=false, updatable=false) private Long id; } @Entity @Table(name = "POST") public class Post { @Id @Column(name = "POST_PK", nullable = false, updatable = false) private Long id; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @JoinColumn(name = "POST_FK", nullable = false) private List<Comment> comments; } Observe that the @JoinColumn on POST annotates a OneToMany Unidirectional relationship with COMMENT. Also, this relationship describes the foreign key (POST_FK) as 'nullable=false' Exception: [EL Warning]: 2018-05-16 11:37:44.234--UnitOfWork(-427968753)-- Thread(Thread[main,5,main] )--Local Exception Stack: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.6.6.WAS): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLIntegrityConstraintViolationException: Column 'POST_FK' cannot accept a NULL value. Error Code: 20000 Call: INSERT INTO COMMENT (COMMENT_PK) VALUES (?) bind => [3] Query: InsertObjectQuery(model.Comment@8a02a358) at org.eclipse.persistence.exceptions.DatabaseException.sqlExceptio n(DatabaseException.java:331) at org.eclipse.persistence.internal.databaseaccess.DatabaseAccessor .executeDirectNoSelect(DatabaseAccessor.java:902) EclipseLink is attempting to INSERT into the COMMENT table as value of NULL for POST_FK. The table was created with 'NOT NULL', so this violates the contraint on this column and throws an exception.
Problem conclusion
The fix for this APAR changes the EclipseLink implementation and involves an update to the thirdparty source. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=391279 This fix is currently targeted for WebSphere Application Server 9.0.0.10 and WebSphere Liberty 18.0.0.4.
