title: Looking for java SFTP modern library, not jsch
body: <p>The "jsch" based implementation works for me.<br/>
  But it looks not modern one due to using Vector (old style Java collection).<br/>
  I found that the other implementations are less popular and not documented.<br/>
  Can you recommend implementation of SFTP library that he/she has good experience with it.<br/>
  Thanks.</p>
