Diff module should not operate directly with views since the view hierarchy lock is not acquired in this way:

        editorPane.getDocument().render(new Runnable () {
            @Override
            public void run() {
                try {
                    View rootView = Utilities.getDocumentView(editorPane);
                    int lineNumber = Utilities.getLineOffset((BaseDocument) editorPane.getDocument(), editorPane.getDocument().getLength());
                    if (lineNumber > 0) --lineNumber;
                    View view = rootView.getView(lineNumber);
                    Rectangle rec;
                    if (view != null && (rec = editorPane.modelToView(view.getEndOffset() - 1)) != null) {
                        height[0] = (int) (rec.getY() + rec.getHeight());
                    }
                } catch (BadLocationException ex) {
                    //
                }
            }
        });

Instead please use editorPane.modelToView() / viewToModel() methods.
