Ok, thanks: I've updated the jar file linked from the xrootd page. Very
nice that we have a windows client now, too....
BTW, you can't send mails with large attachments to the mailing list. It
will bounce them. (And in general sending large attachments to mailing list
is bad practice.) You can probably just stick any future update files
someplace at SLAC and send me the location so I can put it in the xrootd
web area...
