I don't know, the Java guys are pretty good about making sure their
API works consistently across all platforms, or at least documenting
the cases where it wouldn't.
I would start with a read only descriptor and get it into the field.
You could always have a runtime property that controller using read
or write descriptors.

It is unclear if you need to open them for writing. The unix specs
clearly allow you do call fsync on ANY file descriptor.
The Linux docs seem to imply that a file descriptor opened for write
is required.
The Java specification allows it on ANY file descriptor as well -
this should be the only one that matters.
AIX docs say that fd opened for write is required... one of the
error codes is
"EBADF The FileDescriptor parameter is not a valid file descriptor
open for writing."
Java can't do much if the underlying OS doesn't support it, so it
looks like we need to open for writing to sync.
