Paul commented on VFS-398:
--------------------------

We have been waiting for 2.1 a release to fix this bug for over a year and a half.  It cripples our app that uses webdav and sftp (both are effected).   There are lots of files starting with "jcr:" on our servers with webdav services.

>          Issue Type: Bug
>    Affects Versions: 2.0
>         Environment: Connecting via FTP to a host running SunOS 5.10

>            Priority: Blocker

> In line 767 of DefaultFileSystemManager.java the UriParser's extractScheme() method is called:
>         String scheme = UriParser.extractScheme(buffer.toString());
> This code was added in revision 780730
> http://svn.apache.org/viewvc?view=revision&revision=780730
> It is not clear to me why this change was made.
> For the FTP provider, buffer contains a plain file name (i.e. without a path and definitely not in URI form)
> A colon is a valid character for a file name.
> However a colon will be interpreted as a URI scheme name.
> This causes an exception when the resolved path is checked using AbstractFileName.checkName()
> Sample code:
> FileObject fo = VFS.getManager().resolveFile("ftp://user:pass@host/some/path/some.file");
> fo.getParent().getChildren();
> If /some/path/ contains a child such as PREFIX:SUFFIX then an exception is thrown:
> Exception in thread "main" org.apache.commons.vfs2.FileSystemException: Invalid descendent file name "PREFIX:SUFFIX".
> 	at org.apache.commons.vfs2.impl.DefaultFileSystemManager.resolveName(DefaultFileSystemManager.java:791)
> 	at org.apache.commons.vfs2.provider.AbstractFileObject.getChildren(AbstractFileObject.java:710)
> 	at org.apache.commons.vfs2.provider.ftp.FtpFileObject.getChildren(FtpFileObject.java:420)
> Therefore calling code is unable to list the children of the specified folder.
