-/**
-
-   The <code>OnlyOnceErrorHandler</code> implements log4j's default
-   error handling policy which consists of emitting a message for the
-   first error in an appender and ignoring all following errors.
-
-   <p>The error message is printed on <code>System.err</code>. 
-
-   <p>This policy aims at protecting an otherwise working application
-   from being flooded with error messages when logging fails.
