CommandProcessor should return DriverResponse

For reference here is how i want to use this:

Currently:
HWISessionItem.java
private List<Integer> queryRet;
private List<String>  queries;

public void runQuery() {
  //for each query in queries
   if (instanceof driver) {
      //other stuff here
     queryRet.add( qp.run(cmd) );
   } else {
      queryRet.add(proc.run(cmd_1)  );
   }
}

So I would like to refactor and use DriverResponse.

private List<DriverResponse> queryRet;
private List<String>  queries;

public void runQuery() {
  //for each query in queries
   
   if (instanceof driver) {
      //other stuff here
     queryRet.add( qp.run(cmd) );  //<--- this is fine
   } else {
      queryRet.add(proc.run(cmd_1)  ); <--this returns an int.
   }
}
