That Javadoc reads "Be sure to read the FAQ entry relating
to parameterized logging <<a moz-do-not-send="true"
href="https://www.slf4j.org/faq.html#logging_performance"
rel="noreferrer" target="_blank">https://www.slf4j.org/faq.<wbr>html#logging_performance</a>>.
Note that logging statements can be parameterized in
presence of an exception/throwable <<a

href="https://www.slf4j.org/faq.html#paramException"

which describes that behavior (which applies to all levels
of logging with slf4j).<br>
