> 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]
