Michał Sobkiewicz commented on LOG4J2-378:
------------------------------------------
Hello again! My problem was caused by incorrect configuration.
What I missed is that during log4j auto initialization,
{{Log4jServletContextListener}} is being registered _after_ listeners declared
within web.xml. You can reorder processing of web-fragments by using
{{<absolute-ordering>}}, but you can't make them to be processed before web.xml
(according to [Servlet 3.0
Spec|http://download.oracle.com/otndocs/jcp/servlet-3.0-fr-oth-JSpec/] / 8.2.2
Ordering of web.xml and web-fragment.xml / 1b).
Because of incorrect ordering, Spring's
{{ContextLoaderListener#contextDestroyed}} was being invoked after
{{Log4jServletContextListener#contextDestroyed}} during server's shutdown.
Nested call to {{LogFactory.getLog}} within the former one was causing
"/actual/catalina/base/logs/$\{web:contextPath\}.log" file to be created (log4j
web context was already destroyed, so $\{web:contextPath\} couldn't be
resolved).
Sorry for misleading!

> URL: https://issues.apache.org/jira/browse/LOG4J2-378
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.0-beta8, 2.0-beta9
> Environment: Issues occurs on Win7/64 system under Tomcat 7.0.42 /
> Oracle JDK 1.7.0_25; fails to occur on RHEL 5.2 system under Tomcat 7.0.26 /
> Oracle JDK 1.7.0_03
> Reporter: Eric Schwarzenbach
>
> In a webapp I'm setting a system property in my apps ServletContextListener,
> and using that system property in my log4j2.xml file, like so:
> {code}
> <appender type="FastFile" name="File"
> fileName="${sys:catalina.home}/logs/${sys:application-name}.log">
> {code}
> On my Windows machine, a log file named "${sys." (always 0 bytes) is being
> created instead of a log file with the application-name. The same war
> deployed on one of our linux servers does not create a ${sys." file and
> instead creates a log file with the intended application-name.
> I should note that the files DO appear in the directory that
> sys:catalina.home should resolve to. They appear elsewhere when I don't use
> sys:catalina.home so I'm quite sure that this variable is resolving correctly
> and it is the sys:application-name which is the problem.
