      A DESCRIPTION OF THE PROBLEM :
      UnixNativeDispatcher.fchmodatNoFollowSupported, added by JDK-8357425, unconditionally returns false on Linux. Historically, that has been accurate. However, glibc 2.32 (2020) added emulation support, and the kernel gained native support in Linux 6.5 (2023). So, a Linux system should be probed for fchmodat AT_SYMLINK_NOFOLLOW support.
