SWT should override the equals method to compare the IDispatch addresses. 
Please enter a bug report against Platform SWT to request this.

Note, rather than calling av.getUnknown, you should call av.getDispatch.

I don't believe there is a simple way for me to compare two OLEAutomation 
objects to find out if they reference the same IDispatch.
 
The best I've come up with using the public functions is the following, 
but it is VERY inefficient:
 
    public static boolean areEqual(OleAutomation a, OleAutomation b) {
        Variant av = new Variant(a);
        Variant bv = new Variant(b);
        IUnknown au = av.getUnknown();
        IUnknown bu = bv.getUnknown();
        int ai = au.getAddress();
        int bi = bu.getAddress();
        return ai == bi;
    }
Is there an alternative?
