If two users complete the same task at the same time, one of the users will get an exception stating that the entity was already updated in another transaction. Activiti does optimistic locking on it's entities.

Thanks for suggestion,

If they use processInstanceId for querying task, there will be no exception. Thanks to tijs.

List taskList= taskService.createTaskQuery().processInstanceId(processId).list();

Every user will get his own set of task,

Thanks and Regards
