Description

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.
