Major Description
The patch changes the behavior of Log4JLogChute and JdkLogChute such that the log level is only set if the coresponding runtime property is set. for example 'runtime.log.logsystem.log4j.logger.level'. Beforet this change, log level was set to 'WARN' if the level wasn't set with a property, which would override logger config file settings if the logger was configured before initializing velocity.
