 Review comment:
   @eolivelli there are several overload methods, what are relevant is as below
   
   ```java
   public void error(String format, Object... arguments);
   public void error(String msg, Throwable t);
   ```
   
   I think
   
   ```java
   LOG.error(String.format("... %s", e.getMessage()), e);
   ```
   
   is also a valid fix.
