Are there any guidelines on how long you can keep a filereader open on a
file for? What exactly is java doing when it opens a filereader? I think
some operating systems will force the connection shut after a certain amount
of time but not sure.

If it's a local file I don't see why. If it's a network connection it
may need some kind of "keepalive"; that will depend on the specific
protocol. In the case of HTTP I know there's a Keepalive: 1 HTTP
header. In the case of others (FTP, local network file sharing
protocols like Samba and NFS, etc.) I don't have a clue, sorry. :)

I am not aware of any operating system that will "timeout" open files.
