Sakit Atakishiyev commented on LOG4J2-1902:
-------------------------------------------
public void start(final Configuration config) {
LOGGER.debug("Starting LoggerContext[name={}, {}] with configuration
{}...", getName(), this, config);
if (configLock.tryLock()) {
try {
if (this.isInitialized() || this.isStopped()) {
if (this.configuration.isShutdownHookEnabled()) {
setUpShutdownHook();
}
this.setStarted();
}
} finally {
configLock.unlock();
}
}
setConfiguration(config);
LOGGER.debug("LoggerContext[name={}, {}] started OK with configuration
{}.", getName(), this, config);
}
from this code context first check default configuration shutdown hook property
and enable thread even we disable in configuration. after that default
configuration is stopped but shutdown hook service continues to work
> log4j2-web does not disable shutdownHook

> I want to disable the shutdown hook, as I'm having trouble in tomcat 7,
> websphere 8, as app logs nothing to the file. The way I'm making it work is
> restarting the application container, which is causing downtime to other
> services running on the same container.
> The doc https://logging.apache.org/log4j/2.x/manual/webapp.html says
> log4j2-web jar is what disables the shutdown hook but not working for me.
