I get the same error with the crosstools-ng-1.7.0. I think its a problem with using the host's jar. I think there is a jar in the crosstools source/build-output that needs to be used instead. Unfortunately, I haven't had time lately to pursue the problem further. Maybe in the next week or two I can look at it.
