Does camel SFTP component support absolute path ?

Issue

• User has a camel route which writes a file to an SFTP server, renaming any existing file.
• It uses an absolute path to the target directory.
• It seems to work fine when there is no existing file.
• It fails when it attempts to rename the existing file.
• Endpoint is defined like

sftp://server//absolute/path/to/dir?
  autoCreate=false&
  disconnect=true&
  fileExist=Move&
  knownHostsFile=KNOWN_HOSTS&
  maximumReconnectAttempts=0&
  moveExisting=%24%7Bfile%3Aname.noext%7D-%24%7Bdate%3Anow%3AyyyyMMdd-HHmmssSSS%7D.%24%7Bfile%3Aext%7D&
  privateKeyFile=PRIVATE_KEY_FILE&
  stepwise=false&
  strictHostKeyChecking=true&
  throwExceptionOnConnectFailed=true&
  username=USERNAME

• The unescaped moveExisting value is

  ${file:name.noext}-${date:now:yyyyMMdd-HHmmssSSS}.${file:ext}

• User face following error when using this endpoint

• Could it be confirmed if the Camel SFTP component supports absolute path?
