Claude Brisson created SLF4J-459: ------------------------------------ Summary: MDC to return previous values Key: SLF4J-459 URL: https://jira.qos.ch/browse/SLF4J-459 Project: SLF4J Issue Type: Improvement Components: Core API Affects Versions: 1.8.0-beta4 Environment: The put(key, value) method in MDC and MDCAdapter could easily return the previously stored value, or null if not found, since this value is returned by the underlying map. Plus, the change is fully backward compatible. This addition eases the implementation of stackable contexts by client applications, without the need of an additional map lookup to fetch the current MDC key value for latter restoration when the client context is popped up.
