@FlorianHockmann The previous fix didn't work. As @cdegroc pointed out, it was caused by the version incompatibility in JanusGraph and TinkerPop. The ultimate solution would be to upgrade TinkerPop version. Since this issue can be reproduced on 0.6 too, I'd like to fix it by downgrading snakeyaml first and backport it to 0.6.

Sure, makes sense.
