Reproducer:
import module jdk.jfr;

void main() {
    var r = new Recording();
    r.close();
    var fr = FlightRecorder.getFlightRecorder();
    System.out.println(fr.getRecordings().size());
    r.copy(false);
    System.out.println(fr.getRecordings().size());
}

Expected output is:
0
0

Current output should be:
0
1

FlightRecorder::getRecordings() should only return available recordings, not closed.
