Ah...I think this might be due to the fact that the SSHJ version (0.8.1) is on an [older version of Bouncycastle](https://github.com/shikhar/sshj/blob/v0.8.1/pom.xml#L209). I'll submit a PR to try to update to the latest version.
In the meantime, could you try a local build in which you explicitly exclude sshj from the jclouds-sshj driver and add in <dependency> <groupId>net.schmizz</groupId> <artifactId>sshj</artifactId> <version>0.9.0</version> </dependency> as a dep. You should be able to _remove_ the explicit Bouncycastle dep you added. --- Reply to this email directly or view it on GitHub: https://github.com/jclouds/jclouds/pull/273#issuecomment-33970133
