SLF4J Loggers define up to two arguments for precisely this purpose: https://www.slf4j.org/apidocs/org/slf4j/Logger.html#error(java.lang.String,java.lang.Object https://www.slf4j.org/apidocs/org/slf4j/Logger.html#error(ja......) > This form avoids superfluous string concatenation when the logger is disabled for the ERROR level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for ERROR. The variants taking one and two arguments exist solely in order to avoid this hidden cost.
