Robert Elliot commented on LBCLASSIC-31:
----------------------------------------

I'm probably missing something, but if you don't want the stacktrace, why pass the exception to the info method?

> It would be useful if under certain very specific conditions, logback avoided printing stack traces.
> In particular, in server applications IOEXceptions are thrown under normal conditions, such as when the client closes its connection to the server.
> Typical code would look like:
>   try {
>         event = (AuditEvent) ois.readObject();
>   } catch (java.io.EOFException e) {
>         logger.info("Caught java.io.EOFException closing connection.", e);
>         break;
>   } catch (IOException e) {
>         logger.info("Caught java.io.IOException: ", e);
>         break;
>   } catch (ClassNotFoundException e) {
>        logger.error("Unexpected ClassNotFoundException.", e);
>        writeResponse(e);
>        break;
>   }
> Most of the time we would like to avoid printing the stack trace for the two exceptions but not the third.
> Possible solution:
>  Marker ignoreST = MarkerFactgory.getMarker("IGNORE_STACK_TRACE"); 
>  logger.info(ignoreST, "Caught java.io.EOFException closing connection.", e);
> Note that even if most of the time we would like to avoid printing the stack trace, it should still be possible to allow st printing by overriding some parameter.
