Issue #839 JavaLogFactory ConcMod (#840)
* Issue #839 JavaLogFactory ConcMod Removing support for esapi-java-logging.properties file from baseline. ConfigurationException is thrown if file is found on the path at runtime. Exception message links to a wiki page with instructions on how to configure the application instance. * JavaLogFactory Cleanup Removing unused imports. Consolidating String duplication to a class constant.
