PieChart fails to initialize in a background thread. To reproduce, use the newly developed NodeInitializationStressTest:

```
    @Test
    public void pieChart() {
        test(() -> {
            PieChart c = new PieChart();
            c.getData().setAll(createPieSeries());
            return c;
        }, (c) -> {
            c.getData().setAll(createPieSeries());
            accessChart(c);
        });
    }
```

Exception:


java.lang.ArrayIndexOutOfBoundsException: Index 40 out of bounds for length 40
