[jdk21u-dev] RFR: 8343342: java/io/File/GetXSpace.java fails on Windows with CD-ROM drive

[Taizo Kurashige]

Hi all,

This is a backport of JDK-8343342: java/io/File/GetXSpace.java fails on Windows with CD-ROM drive

Original patch does not apply cleanly.
GetXSpace.java in jdk21 includes tests when the SecurityManager is enabled.
When testing using class DenyFSA, the df command executed in getCDDriveSpace occurs  java.security.AccessControlException. To prevent this, I modified testVolumes() to change the timing of the SecurityManager set.

Testing: java/io/File/GetXSpace.java on Windows Server 2019 where drive C is a normal local disk, drive D is an unmounted iso CD-ROM drive, and drive F is an iso mounted CD-ROM drive

Thanks.
