Description
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());
