Summary 0002645: NPE in quercus _caucho_is_modified on bugs.caucho.com
Description The page http://bugs.caucho.com/my_view_page.php [^] is refreshing itself due to the header
  <meta http-equiv="Refresh" content="1800;URL=my_view_page.php" />
and having that page open in my browser, sometimes I see this Exception:

java.lang.NullPointerException

Of course, I don't recognize this immediately when it happens, but when I refresh the page the exception does not occur any more.
