[vfs] Bogus cache after directory move with SFTP

[Jörg Schaible <Jo...@Elsag-Solutions.com>]

Hi folks,

the cache of VFS gets corrupted for a SFTP file system after moving a directory. Details can be found in http://issues.apache.org/jira/browse/VFS-172.

In short: After moving a folder in SFTP any child/subfolder at the old location still claims to exist. Even if you try to create the subfolder again, nothing happens on the server. You may even create and write into a file of such a non-existing subfolder - without any raised Exception.

Does anybody know a workaround for the situation? Calling System.gc() multiple times is not really an option.
