Trying to create AsyncSignalEventCommand through REST API fails with ClassCastException:

1. Job execution of a job (here: 52) went into ERROR state
2. Retrieve the job details through REST

   $ curl -X GET "http://localhost:8080/kie-server/services/rest/server/jobs/52?withErrors=false&withData=true" -H "accept: application/json"
   {
     "request-instance-id": 52,
     "request-status": "ERROR",
     "request-business-key": null,
     "request-message": "Ready to execute",
     "request-retries": 0,
     "request-executions": 4,
     "request-command": "org.jbpm.process.core.async.AsyncSignalEventCommand",
     "request-scheduled-date": {
       "java.util.Date": 1638222484712
     },
     "request-data": {
       "processInstanceId": 100040,
       "Signal": "a49e2b1b-5a59-407e-98f9-b05452303bfe",
       "deploymentId": "com.redhat.cee:wih-project:1.0",
       "Event": null
     },
     "response-data": {},
     "request-errors": null,
     "request-container-id": "com.redhat.cee:wih-project:1.0"
   }
   

3. Try to create a new job through REST with the same request-data:

   curl -X POST "http://localhost:8080/kie-server/services/rest/server/jobs?containerId=com.redhat.cee%3Awih-project%3A1.0" -H "accept: application/json" -H "content-type: application/json" -d "{ \"job-command\" : \"org.jbpm.process.core.async.AsyncSignalEventCommand\", \"request-data\": { \"processInstanceId\": 100040, \"Signal\": \"a49e2b1b-5a59-407e-98f9-b05452303bfe\", \"deploymentId\": \"com.redhat.cee:wih-project:1.0\", \"Event\": null }}"
   

4. Execution of this job fails:
