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
