I just upgraded from 1.2.6 to 2.0-M5 and now I'm getting an exception from DriverManagerDataSource becuase it seems that PropertyPlaceholderConfigurer didn't substitute it's values.

Here's the relevent config:
Code:
<beans>
  <bean id="propertyConfigurer"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:/jdbc.properties</value>
            </list>
        </property>
  </bean>
  
  <bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="url">
        <value>${jdbc.url}</value>
    </property>
    <property name="driverClassName">
        <value>${jdbc.driverClassName}</value>
    </property>
    <property name="username">
        <value>${jdbc.username}</value>
    </property>
    <property name="password">
        <value>${jdbc.password}</value>
    </property>
  </bean>
...  
</beans>
And here's the log output:
