JavaFx sequence can not convert to Java array

Question

for example
var data= [
["Mary", "Campione",
"Snowboarding", "Campione", "Campione"],
["Alison", "Huml",
"Rowing", "3", "false"]
def swingTable = new JTable(v, columnNames);
The array in javafx is Sequence so it is causing troubles when using java apis, I dont get it why javafx use sequence instead, any idea on how to deal with it? thank you in advance.

Finally succeed, share my sample in case anyone want to have as a reference. Have not find a nice way to initialize nativearray of nativearray during declaration although:
var columnNames= ["Column1",
"Column2",
"Column3",
"Column4",
"Column5"] as nativearray of String;
var d1 = ["Need", "to",
"kick", "Flex's", "***"] as nativearray of Object;
var d2 = ["But", "lack",
"javafx", "table", "support"] as nativearray of Object;
var data = TableUtil.createArray(2, 5) as nativearray of nativearray of Object;
data[0] = d1;
data[1] = d2;
var o:Object[];
def swingTable = new JTable( data, columnNames) as JTable;
swingTable.setPreferredScrollableViewportSize(new Dimension(500, 70));
def scrollPane = new JScrollPane(swingTable);
Stage {
scene: Scene {
content: VBox {
content: [
SwingComponent.wrap(scrollPane),
// other FX nodes
public class TableUtil {
public static Object[][] createArray(int i, int j) {
return new Object[i][j];
