bpm:implementation.bpm marked as persistent fails
When using the implementation.bpm element in a switchyard configuration file marked as persistent="true" as shown below:
{code}
...
<bpm:implementation.bpm requires="managedTransaction.Global" processDefinition="ProcessComponent.bpmn" processId="HelloBPMWorld" persistent="true">
<bpm:taskHandler name="SwitchYard Service" class="org.switchyard.component.bpm.task.work.SwitchYardServiceTaskHandler"/>
</bpm:implementation.bpm>
...
{code}
I get the following error:
{code}

{code}
A class path problem pointing to the application not being able to find the mentioned class. I have tried adding the org.drools module to my manifest.mf file as a dependency as explained by JBoss Modules documentation (and JBoss AS 7). Since the JBoss instance I am using is the switchyard-0.6.Final one, and drools modules are where they belong. I have tried by adding a Dependencies: entry in my manifest:
{code}
Dependencies: org.drools
{code}
But still JBoss is unable to find the entities.
So, how do I run persistent processes with SwitchYard?
