How to save the VisualVM OQL result directly into file?

My query results in millions of rows. I have already modified visualvm.conf

-J-DOQLController.limitResults=1000000

Currently, as a workaround I run the query, and copy and paste the result to a file. However, the result puts a lot of strain on my memory. Is there anyway to skip displaying the result to the UI, and just stream the result directly to a file?

My query looks like:

select { obj1: busObj.obj1, ... , objN: busObj.objN }
  from com.my.BusinessObject busObj

You can try something like:

writeToFile()

function writeToFile() {
    var objects = heap.objects("com.my.BusinessObject", false);
    var FileWriterClass=Java.type("java.io.FileWriter");
    var writer = new FileWriterClass("/tmp/out.txt");

    while (objects.hasMoreElements()) {
        var busObj = objects.nextElement();

        writer.write("obj1: "+busObj.obj1+", obj2: "+busObj.obj2+"\n");
    }
    writer.close();
    return { Result: "done" };
}
