StoredProcedureItemReader抛出java.lang.ArrayIndexOutOfBoundsException

Question

当我的程序没有返回任何行时，无法从作业执行中获得控制权。当记录存在时，这可以正常工作。

StoredProcedureItemReader用法的代码片段：

<bean id="storedProcItemReader" 
class="org.springframework.batch.item.database.StoredProcedureItemReader"
    scope="step">
    <property name="dataSource" ref="dataSource" />
    <property name="rowMapper" ref="custRowMapper" />
    <property name="procedureName" value="getAllCustomers" />
    <property name="parameters">
        <list>
            <bean class="org.springframework.jdbc.core.SqlParameter">
                <constructor-arg index="0" value="custId"/>
                <constructor-arg index="1">
                    <util:constant static-field="java.sql.Types.VARCHAR"/>
                </constructor-arg>
            </bean>
        </list>
    </property>
    <property name="preparedStatementSetter" ref="custPreparedStatementSetter" />   
</bean>

抛出异常：
