[jira] [Commented] (LOG4J2-3580) issue while using log4j version 2.17.2

    [ https://issues.apache.org/jira/browse/LOG4J2-3580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17582663#comment-17582663 ] 

Ralph Goers commented on LOG4J2-3580:
-------------------------------------

Well, NoClassDefFoundError means that the org.osgi.framework.BundleReference class cannot be found. The only reason I can think of for that is that somehow the osgi api jar is not on the class path. Log4j expects that it will be provided by the OSGi container. So you will have to determine why that is not happening. Frankly, I am not sure how your app could work at all without that.

In any case, this is not a Log4j problem.
