Spring JPA provider produces wring exception on optimistic lock failure

In case there is failure in optimistic locking I expect JPA entity manager to throw javax.persistence.OptimisticLockingException

Yet when I use spring orm jpa it provides ObjectOptimisticLockingException wh开发者_开发知识库ich is not related with expected one - so the question is, WTF? Do I misunderstand JPA documentation, or did the spring guys ignored standarts?

Most funny thing is that in JUnit test case proper exception is thrown ( Wrapping StaleObjectException ), while in web app it is FUBAR. Spring configuration is reused for unit test.

Here is some code for clarity :

<!-- JPA entity manager configuration -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="${database.driver}"/>
    <property name="url" value="${database.url}"/>
    <property name="username" value="${database.username}"/>
    <property name="password" value="${database.password}"/>
    <property name="testOnBorrow" value="${database.testonborrow}"/>
    <property name="validationQuery" value="${database.validationquery}"/>
</bean>

<bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
    <property name="defaultDataSource" ref="dataSource"/>
</bean>

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="persistenceUnitManager" ref="persistenceUnitManager"/>
    <property name="persistenceUnitName" value="provisioning"/>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="generateDdl" value="true"/>
        </bean>
    </property>
    <property name="jpaPropertyMap">
        <map>
            <entry key="hibernate.dialect" value="${hibernate.dialect}"/>
            <entry key="hibernate.hbm2ddl.auto" value="${hibernate.hbm2ddl.auto}" />
            <entry key="hibernate.hbm2ddl.delimiter.type" value="InnoDB" />
            <entry key="hibernate.show_sql" value="${hibernate.show_sql}" />
        </map>
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

<context:annotation-config/>

<tx:annotation-driven/>

It's not a bug, it's a feature. Spring's HibernateTemplate and its interceptors around repositories translate exceptions into Spring exceptions. The idea is that if you have a Hibernate-based DAO, an iBatis-based DAO or a JDBC-based DAO, they all throw the same types of exceptions, so that the client code doesn't have to care.

See http://static.springsource.org/spring/docs/3.1.0.M2/spring-framework-reference/html/dao.html#dao-exceptions
