How to Disable Horizontal Scroll bar in ComboBox in SWT

问题

I have created a combo Box but I am experiencing a strange behavior, If number of Elements in my Combobox is <= 2, I am unable to see a Horizontal scroll bar.

But if they are more than 2 then I see a horizontal scroll bar automatically pop up. What I would like is, to disable the horizontal scroll bar. This is the code I am using.

preferredResourceCombo = Components.createCombo(controlComposite, SWT.BORDER);
        GridData gridData = new GridData(SWT.FILL, SWT.FILL, true, false);
        gridData.widthHint = 150;
        preferredResourceCombo.setLayoutData(gridData);

        preferredResourceCombo.addVerifyListener(new ComboAutoSelectVerifyListener());

        // preferred resource combo modify listener at bottom of method
        preferredResourceComboViewer = new ComboViewer(preferredResourceCombo);
        preferredResourceComboViewer.setLabelProvider(SelectionItemLabelProvider.getInstance());
        preferredResourceComboViewer.setContentProvider(ArrayContentProvider.getInstance());

I am using the same code everywhere but only here I am getting this behavior.What could be the possible causes?

There's a bug report about this here.

Unfortunately, there is no solution so far.
