Reflections-Spring can't collect saved metadata on bootstrap time

What steps will reproduce the problem?
I reference wiki tutorial about ReflectionsSpring, and do below setup in my 
spring config xml file :
<beans
          ...
          xmlns:reflections="http://org.reflections"
          ...
          xsi:schemaLocation="...
             http://org.reflections http://org.reflections/reflections.xsd">
          ...

          <reflections:component-scan base-package="my.package.prefix"
              collect="true" save="true" parallel="true">

              <!-- sorry for that, a little hackery until next version-->
              <reflections:exclude-filter type="regex" expression="org.springframework.(?!stereotype).*"/>

          </reflections:component-scan>

What is the expected output? What do you see instead?
I expected META-INF/reflections/myBasePackage-reflections.xml,
but nothing happened.

What version of the product are you using? On what operating system?
Version is 0.9.9-RC1

Please provide any additional information below.
I don't use mave in my project, so I don't provide reflections-mave jar.
How Reflections-Spring work to collect saved metadata on bootstrap time?
Is it possible? Thanks.
