Leaky bar chart - bug?

Question

using javafx 1.2
testing javafx.scene.charts
Looks like there is a memory leak
Here is a small bar chart app.
The bars are animated.
They shrink and grow when clicked on.
Keep clicking and the app eventually crashes with the following error
Unexpected exception caught in MasterTimer.process():
java.lang.OutOfMemoryError: Java heap space
Just moving the mouse cursor and hovering over different bars seems to use more and more memory

Same problem here. I have a SystemInformationSimulator that generates random data. Trying to plot this using a LineChart overloads the heap after adding around 40 points.

import javafx.scene.Scene;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.LineChart.*;
import javafx.scene.text.Font;
import javafx.scene.chart.part.NumberAxis;
var numberOfCores = 4;
var system = SystemInformationSimulator{
        hostName: "Schildmeer"
        numberOfCores: numberOfCores
var series: Series[];
for(i in [0..numberOfCores-1]){
    insert Series{ } into series;
var x = 0;
var lowerX = 0;
var upperX = 20;
Timeline {
    repeatCount: Timeline.INDEFINITE
    keyFrames : [
        KeyFrame {
            time : 5s
            canSkip : true
            action: function() {
                system.update();
                for(i in [0..numberOfCores-1]){
                    var point = Data{
                        xValue: x
                        yValue: system.cpuLoad[i]
                    insert point into series.data;
if(x >= 20){
delete series[i].data[0];
lowerX++;
upperX++;
println("inserterd point into series[{i}] with x:{x-1} and y:{point.yValue} series[{i}] has size of {sizeof series[i].data}");
x++;
if(x >= 20){
lowerX++;
upperX++;
}.playFromStart();
