Re: Regression/Error on commons-io FileUtils.copyFile ?

I try to debug it to see what is the problem.

Yes, looks that the timestamp isn't changed. destAttrView.setTimes(...) 
throws an java.nio.file.FileSystemException: 
/mnt/.../ficheros/00000001.tif: Operación no permitida (Not allowed 
operation). Then targetFile.setLastModified(...) returns false.

The mount folder has this options (taken frommount | grep MY_FOLDER) :

cifs (rw,relatime,vers=3.0,cache=strict,username=XXXXX,domain=XXXXX,uid=1000,noforceuid,gid=1000,noforcegid,addr=XXXXXXX,file_mode=0777,dir_mode=0777,iocharset=utf8,soft,nounix,mapposix,rsize=4194304,wsize=4194304,bsize=1048576,echo_interval=60,actimeo=1,closetimeo=1)

Note that this happens on different versions of Ubuntu server (22.04LTS 
and 18.04LTS)
