(fc) FileChannel.force fails on WebDAV file systems (macOS)

ADDITIONAL SYSTEM INFORMATION :
macOS 10.14.6, Tested with Oracle JDK 8u202, 8u221 and 13

A DESCRIPTION OF THE PROBLEM :
Beginning with Java 9 it is no longer possible to call force() on a FileChannel pointing to a file on a mounted WebDAV drive (similar reports for CIFS drives on Linux that I can not confirm).

REGRESSION : Last worked in version 8u221

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Mount a WebDAV-Drive (in Finder press ⌘K). For Testing you can use a URL obtained from the upper right corner of webdavserver.com
2. Run attached test class, provide an absolute path to a any existing or nonexisting file inside the mounted drive as arg[0]

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No exception
ACTUAL -
java.io.IOException: Invalid argument
