Hi gang, the docs of VFS praise VFS.getManager() as simplest possibility to work with VFS. However, this setup uses a SortRefFileCache as default implementation. This caused our server app to fail, since it means that FileObject instances are only garbage collected if the Java process runs out of memory. However, if the instance refer some other limited resource (in our case for SFTP socket connections to the SFTP server) they may never be released. Our SFTP server simply runs out of available connections over time.
Therefore we should possibly reconsider the default choice and use the WeakRefFileCache instead. Since the FileObject instances are often linked anyway with their parent/children references, the weak references are normally not freed while the client has one reference left. IMHO this behaviour matches the "simplest" (and less error-prone) approach using VFS.getManager() most.
