      It is possible to create bpmn file by Modeler that contains this:

       <bpmn:exclusiveGateway id="ExclusiveGateway_0aw668v" name="IDs result" default="SequenceFlow_10nmw69">
          <bpmn:extensionElements>
            <camunda:executionListener class="" event="start" />
          </bpmn:extensionElements>

      or this:

      <bpmn:sequenceFlow id="SequenceFlow_18trlp5" sourceRef="UserTask_verifyIDs" targetRef="ExclusiveGateway_0aw668v">
          <bpmn:extensionElements>
            <camunda:executionListener class="" event="take" />
          </bpmn:extensionElements>
        </bpmn:sequenceFlow>

      Notice the empty class attribute. You can deploy this kind of bpmn, error happens at runtime.

        This is the controller panel for Smart Panels app

            Hi Petr,

            thanks for your patience.

            What is the problem?

            • When a service task with empty class attribute is deployed, an exception occurs: 
              ENGINE-09005 Could not parse BPMN process. Errors: 
* One of the attributes 'class', 'delegateExpression', 'type', or 'expression' is mandatory on serviceTask.
            • When a user task with an execution listener is deployed and the listener type is class but the value is empty, no exception is thrown on deployment level
              • An exception is only thrown when executing the process

            This behavior seems to me not as user friendly as it could be so I have forwarded it for decision-making.

            Stay tuned!

            Cheers,
            Tassilo
