/**
 * Need to figure out exactly what's wrong without this class and add details to the docs.
 *
 * jul-to-slf4j bridge cannot replace classes in the java.util.logging package to do the redirection
 * statically as it does for the other bridge implementations. Instead, it has to register a handler on
 * the root logger and listen for logging statements like any other handler. It will then redirect
 * those logging statements.
