SLF4J / SLF4J-557 [In Progress] MDCCloseable: not a great fit for a try-with-resources statement ============================== Here's what changed in this issue in the last few minutes.

Your test proves my point. That is, the MDC is a concept not suited to be seen as a Closeable resource, because it leads to miss pieces of information in catch blocks.   In a real world scenario, you would have: {code:java} try (MDC.MDCCloseable closeable = MDC.putCloseable(key, val)) { ... } catch (IllegalStateException e) { log.error("logging the error", e); // MDC will not be attached to this log at runtime! }{code}     ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
