> Found some incorrect usage of sl4j in class {{Volume/Bucket/KeyProcessTemplate.class}}.
> For Example line100 in {{VolumeProcessTemplate#handleCall(}},
> We use {{LOG.error("illegal argument. {}", ex);}} to print error info. It will invoke {{Logger.error(String msg, Throwable t)}} not {{Logger.debug(String format, Object arg1)}}.
> Redundant characters '{}' will be printed in exception log.
> The correct usage of this should be {{LOG.error("illegal argument. {}", ex.toString());}}
