Spring Batch JdbcPagingItemReader seems not paginating

Following Hansjoerg Wingeier's suggestions I decided to use a JdbcCursorItemReader and solved the UncategorizedSQLException by setting verifyCursorPosition=false as described here.

This is the final configuration for JdbcCursorItemReader:

<bean id="jdbcCursorItemReader" class="org.springframework.batch.item.database.JdbcCursorItemReader" scope="step">
        <property name="dataSource" ref="dataSource" />
        <property name="sql">
            <value>
                        <![CDATA[
