      Two workaround possible:

      1. activate specific kie-server marshalling flag (STANDARD practice on kie-server)
      2. Rename com.Applicant or input node Applicant to avoid name clash (e.g.: rename input data node from Applicant to applicant lower case)

      Jackson is deserializing the object and it is trying to use com.Applicant object because of name clash.
