>          Components: All
>    Affects Versions: 5.1.0.CR1

> private JPAKnowledgeFactoryService                           jpaKnowledgeServiceProvider;
> in "JPAKnowledgeServiceBean" is not initialized. It used to be by:
>     protected void initDao() {
>         ...  ...  ...
>         jpaKnowledgeServiceProvider = node.get( JPAKnowledgeFactoryService.class );
>         if ( jpaKnowledgeServiceProvider instanceof JPAKnowledgeProviderLocalClient ) {
>             JPAKnowledgeProviderLocalClient local = (JPAKnowledgeProviderLocalClient) jpaKnowledgeServiceProvider;
>             local.setCommandServiceClass( SpringSingleSessionCommandService.class );
>         } else {
>             throw new RuntimeDroolsException( "JPAKnowledgeService is not instance of: " + JPAKnowledgeProviderLocalClient.class.getName() );
>         }
>     }
> but now this code is commented out [ in the latest SNAPSHOT as well ]. Therefore both:
>     public StatefulKnowledgeSession newStatefulKnowledgeSession() {}
> and
>     public StatefulKnowledgeSession loadStatefulKnowledgeSession(final int sessionId) {}
> FAIL, since they use jpaKnowledgeServiceProvider to create / load Sessions:
>          return jpaKnowledgeServiceProvider.newStatefulKnowledgeSession..
>          return jpaKnowledgeServiceProvider.loadStatefulKnowledgeSession..
> -------------------------------------------------------------------------------------------------------------------
> I understand "SpringSingleSessionCommandService" was removed, but this is not the reason to document the whole thing as it breaks the code base that depends on it.
> -------------------------------------------------------------------------------------------------------------------
> If "JPAKnowledgeServiceBean" is deprecated, or a different configuration required, please advise. Is it documented?
