    jbpm-jpdl3.2.2 TaskMgmtInstance.createTaskInstance()

      Hi,

      we are migrating from jbpm-3.0.4 to jbpm-jpdl-3.2.2 - yes we missed 3.1.x :(

      Most things work fine so far, however I have an "old" TestClass which creates a TaskInstance as follows:

      TaskInstance taskInstance = processInstance.getTaskMgmtInstance().createTaskInstance();


      This works fine in jbpm-3.0.4 and jbpm-3.1.4. However in jbpm-jpdl-3.2.2 this brings a NullPointerException. Here is the relevant code from jbpm-jpdl-3.2.2 org.jbpm.taskmgmt.exe.TaskMgmtInstance:

      ...
      public TaskInstance createTaskInstance() {
      
       return createTaskInstance(null, (ExecutionContext)null);
      
      }
      
      public TaskInstance createTaskInstance(Task task, ExecutionContext executionContext) {
      
       // instantiate the new task instance
      
       TaskInstance taskInstance = instantiateNewTaskInstance(executionContext);
      
      
      
       // bind the task instance to the TaskMgmtInstance
      
       addTaskInstance(taskInstance);
      
       // ... add a reference to the process instance
      
       taskInstance.setProcessInstance(executionContext.getProcessInstance());
      
      ....
      


      Obviously a call to TaskMgmtInstance.createTaskInstance() has to fail on the following line (because 'executionContext' is null):

      taskInstance.setProcessInstance(executionContext.getProcessInstance());
      


      What is the reason for that -> bug?
      Is it a known issues? Is there a workaround or fix for that?

      tia,
