[jira] [Updated] (LOG4J2-1098) log4j.shutdownHookEnabled=false from
log4j-web ignored?
[ https://issues.apache.org/jira/browse/LOG4J2-1098?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robin Jansohn updated LOG4J2-1098:
----------------------------------
Description:
In the documentation it says for the System Property 'log4j.shutdownHookEnabled':
Overrides the global flag for whether or not a shutdown hook should be used to stop a LoggerContext. By default, this is enabled and can be disabled on a per-configuration basis. When running with the log4j-web module, this is automatically disabled.
I included the log4j-web module into my Maven project so the shutdown hook should be disabled. During initialization I can see in the debug messages that this is not the case:
DEBUG Starting LoggerContext[name=31484215] from configuration at null
DEBUG Starting LoggerContext[name=31484215, org.apache.logging.log4j.core.LoggerContext@1836523] with configuration XmlConfiguration[location=C:\app\apache-tomcat-8.0.24\wtpwebapps\webapp\WEB-INF\classes\log4j2.xml]...
DEBUG Shutdown hook enabled. Registering a new one.
DEBUG Starting configuration XmlConfiguration[location=C:\app\apache-tomcat-8.0.24\wtpwebapps\webapp\WEB-INF\classes\log4j2.xml]
[...]
During shutdown (more specifically the contextDestroyed method of the ServletContextListener) I try to log some messages but the Logger is already shut down and therefore swallows all log messages (see LOG4J2-658).
Do I need to do something else to disable the shutdown hook?
