Remko Popma updated LOG4J2-493: ------------------------------- Labels: Async (was: ) > Problem with AsyncLogger when web app is deployed/undeployed multiple times > --------------------------------------------------------------------------- > > Key: LOG4J2-493 > URL: https://issues.apache.org/jira/browse/LOG4J2-493 > Project: Log4j 2 > Issue Type: Bug > Components: Core > Affects Versions: 2.0-beta9, 2.0-rc1 > Environment: tomcat 7.0.42 > Reporter: Kireet Reddy > Assignee: Remko Popma > Labels: Async > > When redeploying my application in tomcat multiple times, I get an exception: > {code} > Exception in thread "Thread-29" java.lang.NullPointerException > at > org.apache.logging.log4j.core.async.AsyncLogger.stop(AsyncLogger.java:249) > at > org.apache.logging.log4j.core.async.AsyncLoggerContext.stop(AsyncLoggerContext.java:56) > at > org.apache.logging.log4j.core.LoggerContext$ShutdownThread.run(LoggerContext.java:437) > {code} > This seems to be due to the fact that some initialization code happens in the > class initializer but is undone in the stop() method which is called during > webapp undeployment. This causes issues because in this case the log4j jar is > loaded by the shared classloader ($catalina.home/lib) rather than the webapp > classloader. This means the AsyncLogger class is not re-created during webapp > deployment. > I am using this structure because I have many 3rd party libraries and want to > keep redeployments lightweight. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: log4j-dev-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-dev-h...@logging.apache.org
