I'm sorry that the following code works with both versions.

BpmnModel bpmnModel = repositoryService.getBpmnModel(processDefition.getId());

// Start form
StartEvent startEvent = (StartEvent) bpmnModel.getFlowElement("startevent1");
List<org.activiti.bpmn.model.FormProperty> formProps = startEvent.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}

// Task form
UserTask userTask = (UserTask) bpmnModel.getFlowElement("usertask1");
formProps = userTask.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}

I'm sorry. I did not understand what you really wanted to do.
Do you want to get a list of form properties?

Thank you for your reply.
If you use Activiti6, you can get expressions of form property by using internal api, like this code.

If you use Activiti 5.22, please tell me.

// Start form
org.activiti.bpmn.model.Process process = ProcessDefinitionUtil.getProcess({ProcessDefinitionId});
StartEvent startEvent = (StartEvent) process.getInitialFlowElement();
List<org.activiti.bpmn.model.FormProperty> formProps = startEvent.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}

// Task form
UserTask userTask = (UserTask) process.getFlowElement({ActivityId}, true);
formProps = userTask.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}
