Thanks for the details. I was able to reproduce the problem with Jsch
0.1.41 and the problem is fixed in Jsch 0.1.44.
You can install Jsch 0.1.44 from orbit. You add
http://download.eclipse.org/tools/orbit/downloads/drops/R20110523182458/repository/
as a repository and than you can update jsch. Then you should be able
to use AES-128-CBC keys in PTP. (Please let me know if you have
difficult installing Jsch and need more detailed instructions).
Juno (PTP 6) will ship with Jsch >= 0.1.44. At that point it won't be
required to manually update JSch.
