HSQLDB Уникальное ограничение, вызывающее java.lang.NullPointerException

При тестировании уникального ограничения, которое я добавил в таблицу, оно соблюдается, но вместо исключения или аналогичного ограничения я получаю исключение NullPointerException при попытке создать другой объект, который ломает ограничение, это не кажется правильнымHSQLDB Уникальное ограничение, вызывающее java.lang.NullPointerException

Я использую LiquiBase:

<changeSet id="some-id"> 
    <addUniqueConstraint columnNames="PRIMARY_CODE, SECONDARY_CODE" 
         tableName="FOO" 
         constraintName="CODE_CONSTRAINT"/> 
</changeSet>

но также пытались создать ограничение напрямую, но получить тот же результат

ALTER TABLE FOO 
add CONSTRAINT c1 UNIQUE (PRIMARY_CODE, SECONDARY_CODE);

Я также определил ограничение в моем классе сущностей с помощью аннотаций JPA

@Entity 
@Table(name = "FOO", 
     uniqueConstraints = @UniqueConstraint(columnNames = { "PRIMARY_CODE", "SECONDARY_CODE" }, name = "CODE_CONSTRAINT")) 
@Data 
public class Foo {

Что я здесь отсутствует?

NPE - ошибка. Попробуйте последний снимок HSQLDB, доступ к которому вы можете получить из Maven: https://oss.sonatype.org/content/repositories/snapshots/org/hsqldb/hsqldb/SNAPSHOT/ – fredt

Спасибо fredt - если вы добавите это как ответ Я соглашусь. – Bacon

Правильно ли работает снимок? – fredt

Была такая же проблема с версией 2.3.3. Обновление до 2.3.4 решило его.
