[jira] [Commented] (LOG4J2-146) Log4J 1.2 API implementation
ClassCastException with SimpleLoggerContext
[ https://issues.apache.org/jira/browse/LOG4J2-146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13551188#comment-13551188 ]
Scott Severtson commented on LOG4J2-146:
----------------------------------------
For context, we ran into this on our CI server, where core was not included as a test runtime dependency. Obviously, our apps will be deployed with core :)
> Log4J 1.2 API implementation ClassCastException with SimpleLoggerContext
> ------------------------------------------------------------------------
>
> Key: LOG4J2-146
> URL: https://issues.apache.org/jira/browse/LOG4J2-146
> Project: Log4j 2
> Issue Type: Bug
> Components: log4j 1.2 emulation
> Affects Versions: 2.0-beta4
> Reporter: Scott Severtson
> Priority: Minor
>
> Attempting to use the Log4J 1.2 emulation API without log4j2-core results in the following error and ClassCastException on startup:
> ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogger
> ...
> ... 36 more
> Caused by: java.lang.ClassCastException: org.apache.logging.log4j.simple.SimpleLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext
> at org.apache.log4j.Logger.getLogger(Logger.java:43)
> ... 39 more
> The ERROR is understood, but the exception is not. Apparently, the Log4J 1.2 emulation is dependent on core, instead of just the SPI? I would not have expected this dependency.
