On Windows Server 2019, if the drive retrieved by File.listRoots() is assigned as a CD-ROM drive and the disk is not mounted, GetXSpace.java fails with the following stack and the message "The device is not ready":

This happens because GetDiskSpaceInformationW function in libGetXSpace.c fails to get information about the size of the drive to which a CD-ROM drive is assigned.

Above errors have also been reported at https://github.com/openjdk/jdk/pull/12397#issuecomment-1705164515 but have not been resolved.

GetXSpace.java is a test for File.get-X-Space methods. These methods can get information about the size of the CD-ROM drive. Therefore, if the target drive for the test is a CD-ROM drive, the test should be run without the above errors.
