Local fix

Problem summary

• Actually the problem was with control keys. The Control keys
  i.e. CTRL-T and
  CTRL-Space were not working properly. When we use the CTRL-T to
  activate a hyperlink its not
  activating and Sometimes an exception is thrown.
  Clicking the link with the mouse, however, activates the link as
  expected.
  According to customer while pressin CTRL-T once, it should
  navigate to the first visible
  hyperlink.Instead of that when the customer is pressing CTRL-T
  first time it results with
  no effect,on a page that specifies a stylesheet. Pressing Ctrl-T
  again navigates to the
  first visible hyperlink.
  When Ctrl-T is pressed for the first time on a page without a
  stylesheet, focus is
  transferred to the first visible hyperlink, as expected.
  

Problem conclusion

• This defect will be fixed in:
  1.4.2 SR9
  .
  As the problem was with the navigation of hyperlinks and
  activating the
  hyperlinks, we looked into the two files(JEditorPane.java,
  HTMLEditorKit.java) which are
  responsible for these problems. In JEditorPnae.java we found
  that there are no instructions
  to change the caret position after scrolling to the anchor. And
  in HTMLEditorKit.java we found
  that because of one previous defect(100856)the control is not
  coming to the first visible link
  in the case of using stylesheet and also because of that defect
  its not activating that link also.
  So,regarding setting of caret position we have done some code
  changes. And removed the previous
  defect(100856) and added a condition which will be executed only
  when a stylesheet is used. Actually
  in the case of stylesheet whenever we press CTRL-T , the control
  goes to an invisible link and after
  that control will go to the first visible link on the page. So,
  with the help of Element Iterator we
  skip that invisible link by going to the next element on that
  page.
  .
  To obtain the fix:
  Install build 20070907 or later
