A DESCRIPTION OF THE PROBLEM :
my code in a MPart:
@PostConstruct
public void createComposite(Composite parent) {
parent.setLayout(new GridLayout(1, false));

/* Create the SWT button */
final org.eclipse.swt.widgets.Button swtButton = new org.eclipse.swt.widgets.Button(parent, SWT.PUSH);
swtButton.setText("SWT Button");

/* Create an FXCanvas */
final FXCanvas fxCanvas = new FXCanvas(parent, SWT.NONE) {

@Override
public Point computeSize(int wHint, int hHint, boolean changed) {
getScene().getWindow().sizeToScene();
int width = (int) getScene().getWidth();
int height = (int) getScene().getHeight();
return new Point(width, height);
}
};
/* Create a JavaFX Group node */
Group group = new Group();
/* Create a JavaFX button */
final Button jfxButton = new Button("JFX Button");
/* Assign the CSS ID ipad-dark-grey */
jfxButton.setId("ipad-dark-grey");
/* Add the button as a child of the Group node */
group.getChildren().add(jfxButton);
/* Create the Scene instance and set the group node as root */
Scene scene = new Scene(group, Color.rgb(parent.getBackground().getRed(), parent.getBackground().getGreen(),
parent.getBackground().getBlue()));
/* Attach an external stylesheet */
scene.getStylesheets().add("twobuttons/Buttons.css");
fxCanvas.setScene(scene);

/* Add Listeners */
swtButton.addListener(SWT.Selection, new Listener() {

@Override
public void handleEvent(Event event) {
jfxButton.setText("JFX Button: Hello from SWT");
parent.layout();
}
});
jfxButton.setOnAction(new EventHandler<ActionEvent>() {

@Override
public void handle(ActionEvent event) {
swtButton.setText("SWT Button: Hello from JFX");
parent.layout();
}
});

}

REGRESSION : Last worked in version 21

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1、just use eclipse pde tool to create a sample rcp project in eclipse version 4.32
2、add Javafx libs in MANIFEST.MF graphic editor:
(a) download javafx sdk，copy the four jar:
javafx-swt.jar,
javafx.base.jar,
javafx.graphics.jar,
javafx.controls.jar
(b) create a folder in the rcp project root,called lib or other.
(c) double click to open MANIFEST.MF Graphic Editor:
(d) Build->Extra ClassPath Entries->Add the libs above(choose the jars in the "lib" folder one by one,don't choose the folder itself),
(e) Then Switch to Runtime:
Runtime->ClassPath->Add all the libs above(not New)
(f) copy the code to the SamplePart.java (del the createComposite method,and paste from clipboard)
(g) right click the ".product" file.Run as->Eclipse Application.
(h) and you will see the error messages above.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The Error Will repeat again.
ACTUAL -
error occur again.
