[jira] [Commented] (LOG4J2-167) ClassCastException from SimpleLoggerContext to core.LoggerContext, since it implements spi.LoggerContext

    [ https://issues.apache.org/jira/browse/LOG4J2-167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13579287#comment-13579287 ] 

Ralph Goers commented on LOG4J2-167:
------------------------------------

How did you call Configurator.initialize in such a way that the implementation found in log4j-core couldn't be located?

> When calling Configurator.initialize(<Name>, null, <File>) it calls LogManager.getContext(loader, false) and if no logging implementation can be found this method returns a new SimpleLoggerContext (created by the factory which in turn is created in the static part of the class). This class implements spi.LoggerContext but the Configurator tries to cast it to core.LoggerContext, which fails since SimpleLoggerContext does not extend that class.
