How to wrap a swt label text

I'm trying to wrap this text automatically, but it doesn't wrap. I'm trying with the code below, not sure what's wrong with the code. This is 

protected Control createContents(Composite parent){
    Composite composite = new Composite(parent, SWT.WRAP);
    composite.setLayout(new GridLayout());
    composite.setLayoutData(new GridData(SWT.HORIZONTAL, SWT.TOP, false, false));

    Group group = new Group(composite, SWT.NONE);
    group.setText("my group");
    group.setLayout(new GridLayout(2, false));
    group.setLayoutData(new GridData(SWT.FILL, SWT.TOP, true, false));
    Button button = new Button(group2,SWT.CHECK);
    GridData data = new GridData(SWT.HORIZONTAL, SWT.TOP, false, true, 1, 1);
    button.setLayoutData(data);

    Label label= new Label(group, SWT.WRAP);
    data = new GridData(GridData.FILL_HORIZONTAL);
    label.setLayoutData(data);
    label.setText("my long text is very long, I need to wrap this very long text lalalalalalalalalalalalalala");
}

The composite's layoutdata also needs to have grabExcessHorizontal space set to true, i.e.:

composite.setLayoutData(new GridData(SWT.NONE, SWT.TOP, true, false));

I think the wrapping label and all of its parent composites need to have that.

By the way, the style-bit SWT.WRAP doesn't make sense for class Composite.
