John Vasileff reopened LOG4J2-50:
---------------------------------
Actually, in the original report I was using log4j12-api. It was a puzzle to
determine why your test passed while mine failed. My code looked like:
import org.apache.log4j.Category;
private static final org.apache.logging.log4j.Logger log4j2Logger =
LogManager.getLogger(Log4j2Testing.class.getName());
private static final Category category2 =
Category.getInstance(Log4j2Testing.class);
...
As it turns out, the order in which the loggers were created changed the
result. See LOG4J2-51. I was able to get correct results by flipping the
order of the getLogger/getInstance calls.
In your patch for the SLF4J API, the problems with slf4jLogger are resolved
since SLF4JLogger no longer extends AbstractLogger. But a problem remains with
the getFQCN() logic.
I have a patch to correct this. It builds on the patches in LOG4J2-51. Note:
LOG4J2-51 temporarily causes your new test case to fail, but the forthcoming
patch fixes the root cause.
> Incorrect %C output (FQCN)

> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Reporter: John Vasileff
> Assignee: Ralph Goers
>
> The fully qualified class name must be set correctly to support conversions
> like %C. In some cases, %C information is incorrect. I think this is
> related to AbstractLogger allowing getFQCN() to be overridden. Log methods
> handled by AbstractLogger should have AbstractLogger's FQCN, not that of the
> subclass.
> Example:
> slf4jLogger.info("slf4jLogger test %C."); // works; SLF4JLogger overrides
> this method
> slf4jLogger.info("slf4jLogger test %C.", t); // fails with '?'; handled by
> AbstractLogger
> category2.info("category test %C"); // fails with 'o.a.l.Category'
> Output:
> INFO Log4j2Testing [main] slf4jLogger test %C.
> INFO ? [main] slf4jLogger test %C.
> java.lang.Throwable
> at Log4j2Testing.main(Log4j2Testing.java:22)
> INFO o.a.l.Category [main] category test %C
