Combobox not getting focus in JTable - Java 8

Question

I have a code that used to work in Java 7, but it is not working anymore in Java 8.

SwingUtilities.invokeLater(new Runnable() {
                public void run() {
                    getChargesTable().changeSelection(row, col, false, false);
                    if (getChargesTable().editCellAt(row, col))
                    {
                        Component editor = getChargesTable().getEditorComponent();
                        editor.requestFocusInWindow();
                    }
                }
            }); 

In JAVA 8 the code above only works when debugging. See the result below when I debugged the code:

However, I got this result in a regular run:

As you can see, the combo box in JTable is not select in the second result.

It's weird because it used to work in Java 7. Can someone help me on that?

Thank you,
