      Bug Description:
      BasicTabbedPaneUI is creating htmlViews even when html is not used

      The JavaDoc for BasicTabbedPaneUI says 'The Views (one per tab title requiring HTML
      rendering) are stored in the htmlViews Vector, which is only allocated after
      the first time we run into an HTML tab.' However the code below demonstrates
      that htmlViews are created even when there are no HTML Tabs.

      Expected: this code to run forever
      Actual: eventually an OutOfMemoryError is thrown (due to the htmlViews which
      should never have been created in the first place getting bigger every call
       to setTitleAt - which is related to bug 6670274)

      import javax.swing.*;

      public class Test {
        public static void main(String[] args) {
          SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
              boolean firstTitle = true;
              JTabbedPane tabbedPane = new JTabbedPane();
              tabbedPane.addTab("Title 1", new JLabel("Component"));
              tabbedPane.updateUI();
              while (true) {
                firstTitle = !firstTitle;
                tabbedPane.setTitleAt(0, firstTitle ? "Title 1" : "Title 2");
              }
            }
          });
        }
      }


      }
