Compilation error with b78 not with 77

[Sven Reimers]

The following code worked fine with b77


private void testMethod() {
        XYChart<Number, Number> numberChart = new LineChart<>(new NumberAxis(),
new NumberAxis());
        List<XYChart.Data<Number, Number>> data_1 = new ArrayList<>();
        List<XYChart.Data<Number, Number>> data_2 = new ArrayList<>();
        numberChart.getData().setAll(Arrays.asList(
                        new XYChart.Series<>("Data",
FXCollections.observableList(data_1)),
                        new XYChart.Series<>("Data",
FXCollections.observableList(data_2))));
    }

Compiling with b78 gives me

 error: cannot infer type arguments for Series<>

for the conversion with FXCollections.observableList.

Any ideas if this intentional? Should I report a bug with openjdk?

Thanks

Sven
