Reproducible with the current 7.0.63.
This is an expected behaviour. Context itself is configured by a listener.
The listeners are added by
org.apache.catalina.startup.ContextConfig#processContextConfig() -
parses context.xml files (the global ones and the one for the web
application)
- called from o.a.c.startup.ContextConfig#contextConfig()
- called from o.a.c.startup.ContextConfig#init()
- called from o.a.c.startup.lifecycleEvent() on Lifecycle.AFTER_INIT_EVENT
At the time of the "after_init" event the "before_init" event has
already happened.
For reference, reproduction source code
a sample listener class, to be put into catalina.base/lib/test
[[[
package test;
import org.apache.catalina.LifecycleEvent;
import org.apache.catalina.LifecycleListener;
import org.apache.juli.logging.Log;
import org.apache.juli.logging.LogFactory;
public class TestListener implements LifecycleListener {
private final Log log = LogFactory.getLog(getClass());
@Override
public void lifecycleEvent(LifecycleEvent event) {
log.info("Event: [" + event.getType() + "]");
}
}
]]]
configuration, catalina.base/webapps/examples/META-INF/context.xml
[[[
<Context>
<Listener className="test.TestListener" />
</Context>
]]]
