FilteredTree throwing StackOverFlow Exception

Question

I am using a FilteredTree in my Eclipse plugin view inside a SashForm as follows:

public void createPartControl(Composite parent) {
    Composite container = new Composite(parent, SWT.NONE);

    container.setLayout(new GridLayout(2, false));
    {

            SashForm sashForm = new SashForm(container, SWT.NONE);
            GridData gd = new GridData(SWT.LEFT, SWT.FILL, false, true, 1, 1);
            gd.widthHint = 300;
            sashForm.setLayoutData(gd);
            {
                PatternFilter filter = new PatternFilter();
                FilteredTree tree = new FilteredTree(sashForm, SWT.MULTI | SWT.H_SCROLL
                        | SWT.V_SCROLL, filter, true);

            treeViewer = tree.getViewer();
            }

    }
    {
        browser = new Browser(container, SWT.NONE);
        browser.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, false, 1, 1));

    }

    getSite().setSelectionProvider(treeViewer);
    getSite().getWorkbenchWindow().getSelectionService().addSelectionListener(listener);

    createActions();
    initializeToolBar();
    initializeMenu();
}

Now whenever I use the FilteredTree to filter the contents of tree - it is throwing a StackOverFlowError. I am not able to figure out what is wrong with my implementation?
