Karwasz on 02/Jan/23 11:45 PM [~cowwoc], You can not use method references with a parameter of type {{Object}}. Method references work only if the compiler detects a functional interface type. Therefore you can either introduce a {{Logger#debug(String, Supplier<?>...)}} method (like in Log4j2 API) and write: {code:java} log.debug("{}, {} and {} share a value of {}", () -> first, () -> second, () -> third, this::getExpensiveComputation); {code} (I am not a big fan of this solution) or improve the old {{Logger#debug(String, Object...)}} method and write: {code:java} log.debug("{}, {} and {} share a value of {}", first, second, third, (Supplier<?>) this::getExpensiveComputation); {code} The second solution would probably require a minor version bump (IMHO), the second one can probably be implemented with a default interface method. ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59) _______________________________________________ slf4j-dev mailing list [email protected] https://mailman.qos.ch/cgi-bin/mailman/listinfo/slf4j-dev
