When specifying a SyslogAppender in a property file, and loading
this with the PropertyConfigurator, the PropertyConfiguratorImpl
class instanciates a RemoteSyslogAppender instead of a
SyslogAppender. Why is this done, and not implemented more
dynamicly (like for instance, when a hostname and port are
specified use a RemoteSyslogAppender, otherwise a
SyslogAppender)?
