[jira] [Comment Edited] (LOG4J2-1336) LoggerFactory in 1.2 API
module is not compatible with 1.2
[ https://issues.apache.org/jira/browse/LOG4J2-1336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15220986#comment-15220986 ]

I don't understand how LoggerFactoryBridge could be replaced with LoggerAdapter. Each of the interfaces contain a single method and both take a name, but makeNewLoggerInstance requires the LoggerContext while LoggerAdapter does not. LoggerAdapter is very similar to LoggerFactory but LoggerAdapter cannot be used - it must be exactly the same as the Log4j 1.x LoggerFactory interface.
I suppose if Category extends AbstractLoggerAdapter it might work.

> Project: Log4j 2
> Issue Type: Bug
> Components: log4j 1.2 emulation
> Affects Versions: 2.5
> Reporter: Zbynek Vyskovsky

> LoggerFactory from log4j 1.2 compatibility layer is not compatible with the original 1.2 version. Therefore software which creates its customized loggers is failing due to AbstractMethodError error.
> The fix is quite simple - just keep the original interface. The attached patch continues to support the current method too, but uses different interface name for the functionality so it doesn't clash with 1.2 API.
