[jira] [Resolved] (LOG4J2-50) Incorrect %C output (FQCN)
[ https://issues.apache.org/jira/browse/LOG4J2-50?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ralph Goers resolved LOG4J2-50.
-------------------------------
Resolution: Fixed
Assignee: Ralph Goers
The category problems for the SLF4J api have been corrected. This probably also corrects the problem with log4j-over-slf4j, which is what I assume you meant by category2. However, it would be more appropriate to use the log4j12-api component of Log4j 2.0 if Log4j 2.0 is the underlying implementation.
> Incorrect %C output (FQCN)

> Key: LOG4J2-50

> Project: Log4j 2
> Issue Type: Bug
> Components: Core

> 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
