    Affects Version/s:     (was: 2.1)

> DefaultFilesCache leaks closed filesystems
> ------------------------------------------
>                 Key: VFS-545
>                 URL:

>          Issue Type: Bug
>    Affects Versions: 2.0
>            Reporter: Bernd Eckenfels

> The org.apache.commons.vfs2.cache.DefaultFilesCache does not remove the filesystem specific
cache if a filesystem gets cleared. This leads to the problem that instances if the FileSystem
kept alive after the FileProvider has closed the filesystem. This is not so much a problem
for a smaller number of filesystems configured for a prefix, but it is a problem for layered
or virtual filesystems which get created and destroyed. (See also VFS-544). The more advanced
filesystem caches support clearing the keys (but have other races I think).
> The behaviour is somewhat documented "lifetime of the FileSystemManager", but I don't
think it is expected or required.
