If Desktop.open() fails because the target file has no associated, an 
IOException is thrown with the following error message:
  "A device attached to the system is not functioning."

This is not the correct error message. It should be:
  "There is no application associated with the given file name extension."

Prior to 7u40, a different (but still incorrect) Exception message was shown:
  "Access is denied."

The test leaves the Windows dialog ��How do you want to open this file?�� open on newer Windows versions. See https://bugs.openjdk.java.net/browse/JDK-8204537?focusedCommentId=14395514&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14395514

In Java_sun_awt_windows_WDesktopPeer_ShellExecute() we pass to FormatMessage() the error code returned by ShellExecute() function. This is not correct, since error codes returned by ShellExecute() are not covered by System Error Codes. So we have to pass to FormatMessage() the error code returned by GetLastError() function instead of code returned by ShellExecute().
