> In our production code the exception is actually about
> {{scala.reflect.ManifestFactory$$anon$8}} instead of
> {{scala.reflect.ManifestFactory$$anon$9}} but it's probably the same thing.
> Any idea what caused from 1.2.1 to 1.3.0 that could be causing this?
> We also get exceptions in 1.3.0 for {{scala.reflect.ClassTag$$anon$1}} and
> {{java.lang.Class}}, but I haven't reduced them to a spark-shell reproduction
> yet. We can of course just register these classes ourselves.
