Hello Jacob, FYI, LBCLASSIC-221 was solved in a recent commit [1] to be released in version 1.0.1. The problem you describe is different than the one discussed in LBCLASSIC-221. Could you please file a separate bug report? I've also looked at your patch. However, let's discuss that within the new bug report. Cheers, [1] https://github.com/ceki/logback/commit/26a0a37c -- Ceki http://twitter.com/#!/ceki
