---------------------------------

[~b.eckenfels]: Is it enough to change the DefaultFileSystemManager?  any 
chance you can throw a review on the PR?

> FtpFileObject.getChildren() fails when a folder contains a file with a colon 
> in the name

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

> 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.
