{quote}At least with Java 9+ we should be able to use the new {{ProcessHandle}}
API to get the PID
{quote}
Agreed, though this is not solution to the need to get FileDescriptor.fd and
sun.nio.ch.FileChannelImpl.fd without opening internals which we try to tackle
here. Even if we use the {{ProcessHandle}} API to get the PID we still need to
open the internals to get fd.

You can get them directly from {{{}FileInputStream{}}}, {{FileOutputStream}}
and {{{}RandomAccessFile{}}}. It is a shame there is no equivalent method for
{{{}FileChannel{}}}. There is also the option of redefining {{FileChannelImpl}}
on load (using ASM) to introduce a public method to retrieve the
{{FileDescriptor}} and to simply define our static accessor method (also using
ASM) to access this public method.
But, it might be that we don't really need the file descriptor and can simply
use the {{force}} method on {{{}FileChannel{}}}. We can even do this for
syncing directories, seemingly. Relevant JDK bug thread where this feature was
temporarily broken, tracking a replacement mechanism (that does not yet exist):

So far I haven't found anyone using something different than the reflection
option and complaining about it. Opening here as a place holder for further
future investigations how to refactor this in Cassandra. Open for ideas too
