This would also be beneficial for the scenario of creating several factories from one Configuration, which we discussed a while ago. But obviously this would be a non compatible change for 1.0 clients passing non resettable streams to addMapping(). > What's about a combination of wrapping into BufferedInputStream and adding some javadocs. I think wrapping the input stream into a BufferedInputStream works fine.
