I'm using the latest Version of JEdit (4.3pre17) and the corresponding FTP-plugin (0.9.5) under java 1.6.0_16. When I'm trying to connect to my server using sftp, it fails reporting the following i/o error message:

Cannot list directory: java.io.IOException: com.jcraft.jsch.JSchException: failed to send channel request

Here is the excerpt of the log file:

I also tried this with older versions of JEdit an the ftp plugin, e.g. with JEdit 4.2final and ftp 0.7.3. It doesn't work either, though throwing a different error. I even downloaded the latest version of JSch and replaced the version in the jar directory of JEdit, resulting in the same error message. I don't know what's going wrong, maybe somebody out there has any ideas? Please help cause I'm out of options...

Thanks in advance,
