If this property is not passed to the logging framework at startup,
by default, LogManager reads a configuration file located in the
"JAVA_HOME/jre/lib/ logging.properties" file. This configuration
file defines the default configuration parameters for the logging
framework to work. It is possible to override the default location
and specify our own configuration file by passing a command line
option to the Java runtime as:
java -Djava.util.logging.config.file=configuration file name
RemoteConfigReader.java
