Configuration.java and bad constructor

[Briggs]

The constructor of Configuration is written like this:

Starting at line 90 of org.apache.hadoop.conf.Configuration.java

 /** A new configuration. */
 public Configuration() {
   if (LOG.isDebugEnabled()) {
     LOG.debug(StringUtils.stringifyException(new IOException("config()")));
   }
   defaultResources.add("hadoop-default.xml");
   finalResources.add("hadoop-site.xml");
 }

Now, why would anyone create an IOException and log it like this?  I
was wondering why all these darned exceptions were in my logs.
