--------------------------------------------------------
This is breaking chrooted SFTP with sftp-only on my end as well. What's the
status of this? Is anyone working on this?

> Key: VFS-617
> URL: https://issues.apache.org/jira/browse/VFS-617
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.1
> Environment: Windows 7 Java 7. Failure occured connecting via SFTP to
> a Synology box running DSM 6.
> Reporter: Tim Nickels
>
> The doIsReadable method of SftpFileObject throws an exception if the system
> cannot identify group/owner permissions.......
> Exception in thread "main" org.apache.commons.vfs2.FileSystemException: Could
> not determine if file "sftp://myURI"; is readable.
> at
> org.apache.commons.vfs2.provider.AbstractFileObject.isReadable(AbstractFileObject.java:1761)
> at com.avenca.vfs.VFSUtils.main(VFSUtils.java:41)
> Caused by: com.jcraft.jsch.JSchException: Could not get the groups id of the
> current user (error code: 1)
> at
> org.apache.commons.vfs2.provider.sftp.SftpFileSystem.getGroupsIds(SftpFileSystem.java:263)
> at
> org.apache.commons.vfs2.provider.sftp.SftpFileObject.getPermissions(SftpFileObject.java:317)
> at
> org.apache.commons.vfs2.provider.sftp.SftpFileObject.doIsReadable(SftpFileObject.java:335)
> at
> org.apache.commons.vfs2.provider.AbstractFileObject.isReadable(AbstractFileObject.java:1757)
> The problem is the method is using
> return getPermissions(true).isReadable()
> The folder *is* readable without these permissions, and so should be set to
> return getPermissions(false).isReadable()
> Which correctly allows the system to identify a readable folder without
> adding unnecessary restrictions.
