I reproduced the FormServiceTest.java from chapter 5. Then I tried to start this test with the whole loanrequest.bpmn20.xml, I imported the .jar file in the folder and added this to the librarys,  but I get this error message:

They wrote in the book "At the start of the process, these properties are converted into process variables of the correct type."
What did I wrong or what should I add ?
