V 5.16 - Cancel parallel task with candidate causes referential integrity violation on constraint 'AKT_FK_TSKASS_TASK'

Hello,we have modeled the following workflow:A user requests a vacation. After that an approver can approve this request or the requestor can revoke it. This is the relevant part of our BPMN:<?xml version="1.0" encoding="UTF-8" ?><definitions id="definitions" targetNamespace="http://activit

Updated test and process to simplify testing for you (no internal dependencies from us left and first version actually had some compilation errors):

Test:
<code>
package de.astrumit.pls.process.RevokeSingleTask;

import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.impl.history.HistoryLevel;
import org.activiti.engine.repository.DeploymentBuilder;
import org.activiti.engine.task.Task;
import org.junit.Assert;
import org.junit.Test;

public class RevokeSingleTaskTest {
private static ProcessEngine createEngine(String file) {
ProcessEngine engine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
    .setHistoryLevel(HistoryLevel.FULL).buildProcessEngine();

DeploymentBuilder builder = engine.getRepositoryService().createDeployment();

InputStream processAsStream = RevokeSingleTaskTest.class.getResourceAsStream("/processes/test/" + file
    + ".bpmn20.xml");
if (processAsStream == null) {
   throw new IllegalStateException("Unable to find '/processes/test/" + file + ".bpmn20.xml' on classpath");
}
builder.addInputStream(file + ".bpmn20.xml", processAsStream);

builder.deploy();
return engine;
}

@Test
public void revoke() {
ProcessEngine engine = createEngine("RevokeSingleTask");

Map<String, Object> variables = new HashMap<>();
variables.put("requestor", "req");
variables.put("approverRole", "approver");
engine.getRuntimeService().startProcessInstanceByKey("test", variables);

Task startTask = engine.getTaskService().createTaskQuery().taskDefinitionKey("Request").singleResult();

engine.getTaskService().complete(startTask.getId());

Task revokeTask = engine.getTaskService().createTaskQuery().taskDefinitionKey("Revoke").singleResult();

engine.getTaskService().complete(revokeTask.getId());

Assert.assertEquals(0, engine.getTaskService().createTaskQuery().count());

engine.close();
}
}
</code>

Thanks for the unit-test, I'll try it later today to see the result. In http://forums.activiti.org/content/sticky-how-write-unit-test you can find some tips on writing a test, a zip/gist of such a project is also a good way of providing us a test…
