To whom it may concern,

I had successfully created a human task in jbpm 5.3. I saw it in the jbpm database that it already has a record and its status was 'Reserved'.

After successfully creating a task, the next was to create a record in my database but suddenly it produced an sqlException. Due to

that reason, I would like to delete the jbpm task that was created. I've tried to execute this line:

     taskClient.remove(taskId, userId, responseHandler);

Unfortunately it generated an exception:

java.lang.RuntimeException: Couldn't remove user gvallangca since it isn't a notification recipient

I hope someone could help or give other ideas how to remove the jbpm task I have created. Thanks.
