[logback-dev] [JIRA] Commented: (LBCORE-57) FlushableAppender

[Bruno Navert (JIRA)]

Bruno Navert commented on LBCORE-57:
------------------------------------

One key use-case for this: trigger a manual .flush() when an error (stack trace) occurs in the application. This makes sure that the log file is always up to date in that situation, otherwise it's entirely possible that part of the stack trace is still held in the in-memory buffer, and developers looking at the log file will not see it.
