For anyone else who is still having this issue, the following may help. The embedded SOLR server uses sl4j for logging, which is a facade over other logging frameworks. It achieves this by looking for a 'binding' jar for the implementation framework in the classpath. In my case I had the 'simple' binding (slf4j-simple.jar) in my classpath, which is a non-configurable simple console logging implementation binding that logs everything from INFO up. Simply remove this jar from your class path to default to the NOP logger, or replace it with another logging framework binding jar (such as slf4j-log4j.jar) and configure it as per that framework's requirements.
