      Description



      Name: dbT83986 Date: 03/10/99


      The process I am running using JRE is an RMI server. When
      attempting to access a path that is a removable drive (disk
      drive A:, or local JAZ drive) jre displays a modal dialog
      box saying "there is no disk in the drive, please insert
      a disk into drive DRIVE". This happens on any type of
      file IO (File.isDirectory(), new FileInputStream(), etc.) so
      I have not included specific code. If you click abort, you
      get the IOException.

      Maybe this is not a bug, but my RMI server blocks... what I
      need is for the exception to be thrown without displaying the
      modal dialog box, but I can't figure out how to eliminate this
      behavior.

      Thanks

      REVIEW NOTE 3/10/99 - User responded with more information

      Below is a sample that easily re-creates it, and below that is my actual
      code. But after further searching, I found this bug was already
      reported:

      > bug id: 4089199
      > location: http://developer.java.sun.com/developer/bugParade/bugs/4089199.html

      This really, really needs to be fixed or we need a workaround!!! It would be
      OK if
      it just stopped the executing thread, but I am seeing that it blocks my RMI
      server,
      rendering it useless (this happens if an automatic backup gets kicked off
      and the
      admin forgets to put in a jaz drive, for example).
       
      Help!!!
