SLF4J / SLF4J-421 [In Progress] LoggerWrapper and subclasses perform argument substitution twice ============================== Here's what changed in this issue in the last few minutes. There is 1 comment. View or comment on issue using this link https://jira.qos.ch/browse/SLF4J-421 ============================== 1 comment ------------------------------ Ceki Gülcü on 01/Jul/21 8:55 PM The problem stems from the fact that {{LoggerWrapper}} invokes {{MessageFormatter.format()}} before invoking the {{LocationAwareLogger.log()}} method. A {{LocationAwareLogger}} will in turn invoke {{MessageFormatter.format()}} with the parameters given to it. Hence the behavior, you observe. The solution is not to change {{MessageFormatter}} but simply not invoke {{MessageFormatter.format()}} before calling {{LocationAwareLogger.log()}} *in* {{LoggerWrapper}}. ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
