What is the right usage for <framework:hints>? I've tried to use the below snippet for caching. I don't see any difference with it when seeing the results in Debug console or time taken for UI loading.

<framework:entity-query name="fooQuery" ejbql="from Foo">
  <framework:hints>
      <key>org.hibernate.cacheable</key>
      <value>true</value>
  </framework:hints>
</framework:entity-query>

15:18:12,731 DEBUG [StandardQueryCache] checking cached query results in region: foo_ear,foo-ejbs_jar,asrDatasource.org.hibernate.cache.StandardQueryCache
15:18:12,731 DEBUG [StandardQueryCache] Checking query spaces for up-to-dateness: [fofs]
15:18:12,731 DEBUG [StandardQueryCache] returning cached query results

Any ideas?
