async parallel/inclusive gateways

[rickm]

Hi,

I recently saw in a posting on Tijs' blog (http://bpmn20inaction.blogspot.com/2014/07/activiti-516-feature-preview.html) that the solution for joining of parallel/inclusive gateways had been cleaned up in 5.16 so that it was not necessary to use external frameworks to address the issue of optimistic locks.   This all looks great, but I can't seem to get it to work, I'm still seeing the ActivitiOptimisticLockingException. 

TIA,
Rick

My environment is:
- Activiti 5.16.4
- JRE 1.7
- Tomcat 8.0
- Eclipse Luna
- H2

Below is the content of my source:

BPMN definition attached.

Task_Test.java:
package tasks;

import org.activiti.engine.delegate.DelegateExecution;
import org.activiti.engine.delegate.JavaDelegate;


public class Task_Test implements JavaDelegate {

   @Override
   public void execute(DelegateExecution context) throws Exception {
      System.out.println("Executing activity: " + context.getCurrentActivityName());
      
      Thread.sleep(100);
   }
}

Console:

Hmm that should work. Is this in a regular unit test?
