Martin Walsh created LOGBACK-1337: ------------------------------------- Summary: LogbackMDCAdapter should store mdc in LinkedHashMap to predict order of MDC in %X Key: LOGBACK-1337 URL: https://jira.qos.ch/browse/LOGBACK-1337 Project: logback Issue Type: Improvement Components: logback-classic Affects Versions: 1.2.3, 1.1.11 Reporter: Martin Walsh Assignee: Logback dev list LogbackMDCAdapter uses HashMap rather than LinkedHashMap and so the order of the key value pairs when logging MDC with %X cannot be predicted from one log line to another.  This makes log parsing harder than it has to be.  Using LinkedHashMap would address this as the order of adding to MDC would be preserved.   See [https://github.com/qos-ch/logback/blob/v_1.2.3/logback-classic/src/main/java...] & https://github.com/qos-ch/logback/blob/v_1.1.11/logback-classic/src/main/jav... -- This message was sent by Atlassian JIRA (v7.3.1#73012)
