There are two kind of caches in VFS, one which is responsible to hand
out the FileObject instance itself - where we try hard to hand out
always the same instance for the same file (=filename/filesystem
combination) and another cache inside the FileObject which holds stuff
like children and file informations.
The CacheStrategy tells the system when to refresh the second cache.

Thanks for the code snipped. I tried it with the default
VFS.getManager() (without setting the CacheStrategy) and it works here
with my ftp server as expected.
I am pretty sure for your tests you do not use a delay of 60000, do you?
I tried it with 5000 (5 seconds) and get the events promptly.
But ...... I pointed the monitor to a directory ....

.... ok - got it. Its a bug in the FTPFileObject, unhappily I have no
workaround yet.
Could you please open a ticket at http://issues.appche.org/jira I'll see
if I can fix it soon.


Ciao,
