Yes, my fault. I have tried to stay away from new APIs - the breakage was unintentional.

I'll be more careful in the future, but I do not have any older than 1.6 JVM available
so it is very useful to have the build farm to catch these errors.

If the patch from Mike does not get committed I'll create one tomorrow.
