I created a new JIRA issue: https://issues.apache.org/jira/browse/JAMES-2199
> Improve usage of SLF4J
> ----------------------
>
> Key: JAMES-2199
> URL: https://issues.apache.org/jira/browse/JAMES-2199
> Project: James Server
> Issue Type: Improvement
> Reporter: Daniel Trebbien
> Priority: Minor
>
> As suggested in the SLF4J FAQ (see
> [https://www.slf4j.org/faq.html#logging_performance]) parameterized logging
> can improve the efficiency of logger calls when logging at the specified
> level is disabled.
> When a value is formatted, toString() is called automatically:
> [https://www.slf4j.org/faq.html#string_contents]
> In addition, there are some cases where a format string has incorrect syntax,
> or not enough format args are passed. This can lead to loss of data in the
> logs.
> There are some other cases where the result of String.format() or a string
> buffer/builder are passed to a logger call. Parameterized logging can be used
> even when an extra exception/throwable should be logged:
> [https://www.slf4j.org/faq.html#paramException]
> James Project uses SLF4J 1.7.25, which is affected by a regression introduced
> in SLF4J 1.7.15. See:
> [http://mailman.qos.ch/pipermail/slf4j-user/2017-August/001639.html]
