> When creating a org.apache.commons.vfs2.impl.VirtualFileSystem by org.apache.commons.vfs2.impl.VirtualFileProvider it is tracked as a component. But since VirtualFileProvider is not an AbstractFileProvider and not registered in providers it will never be closed by org.apache.commons.vfs2.impl.DefaultFileSystemManager._closeFileSystem(FileSystem). Also the final instance of VirtualFileProvider does not get closed when the DefaultFileSystemManager gets closed.
> VirtualFileSystem itself does not have critical resources, but its DelegatedFiles are cached so there should be a way to close them.
