This is a bug. Thank you for reporting it. I opened this ticket: https://issues.apache.org/jira/browse/SOLR-4361
Until there is a fix, here are two workarounds: 1. If you do not need any 4.1 DIH functionality, use the 4.0 DIH jar with your 4.1 Solr. -or- 2. Use request parameters without dots: ex. "solrBceDSDriver" instead of "solr.bceDS.driver".
