We would like to turn down the logging level for org.geotools.xml.XMLSAXHandler. Users receive an awful lot of INFO messages in Tomcat's stdout, making it hard to read the other logs.
Logger.info(...) seems to be used as a replacement for debugging with System.out.println(...) in some geotools code, which is not the Level.INFO intend. I think that XMLSAXHandler should use Level.FINEST logging level (or Level.FINER at most).
Not a bug but a RFE, too old and nobody bothered.
