The default initialization algorithm is invoked when the LogManager class is loaded into memory. This class is guaranteed to be loaded before any logger can be used. The exact initialization algorithm is defined as follows: If the log4j.defaultInitOverride system property is set to any other value then “false”, the default initialization procedure (this procedure) […]
