Could you describe in a paragraph your OSGi environment? Even better, do you have an idea or suggestions on how to create a testbed for logback/OSGi integration?

After some restructuring of logging bundles the error went away. Feel free to suspend this issue until someone can reproduce the error in a reliable way.

[ http://jira.qos.ch/browse/LBCLASSIC-120?page=com.atlassian.jira.plugin.syste... ] Ceki Gulcu resolved LBCLASSIC-120. ---------------------------------- Fix Version/s: 0.9.18 Resolution: Fixed As part of the build, logback bundles are now tested to run with Felix. It is this assumed that slf4j+logback bundles work with other OSGi containers as well. Moreover, the tests actually invoke logback configuration via XML.
