    private static class PropertiesUtil.Environment
extends java.lang.Object
    Provides support for looking up global configuration properties via environment variables, property files, and system properties, in three variations:

    Normalized: all log4j-related prefixes removed, remaining property is camelCased with a log4j2 prefix for property files and system properties, or follows a LOG4J_FOO_BAR format for environment variables.
