JClouds Karaf on Windows

Due to the integration of ssh via com.jcraft.jsch in Jclouds 1.7, the karaf feature is no longer working on windows. When trying to create a (aws-ec2) computing service you get the exception you see attached.
The problem seems that on windows the com.jcraft.jsch.agentproxy tries to lookup some classes specific to the win32 implementation.
On a Linux system with karaf 2.4.1, jclouds works correctly.
Jclouds 1.6.3 and karaf 2.4.1 works without problems on windows, too.
Either you should provide in your karaf feature the necessary additional bundles for the windows com.jcraft.jsch.agentproxy or at least make the ssh agent not break the complete functionality as it is optional to use as I understand.
