Summary: The clearReferencesLogFactoryRelease removes all
loggers in the JVM (instead of only removing all
loggers of the Web application that is being
undeployed)
Product: Tomcat 6
Version: 6.0.29
Platform: All
OS/Version: All
Status: NEW
Severity: regression
Priority: P2
Component: Catalina
AssignedTo: [email protected]
ReportedBy: [email protected]
In Tomcat 6.0.29, there's a new parameter in WebappClassLoader:
clearReferencesLogFactoryRelease
It is by default true, and executes the following code when undeploying a web
application:
// Clear the classloader reference in common-logging
if (clearReferencesLogFactoryRelease) {
org.apache.juli.logging.LogFactory.release(this);
}
The called method on JULI does the following:
java.util.logging.LogManager.getLogManager().reset();
Which basically removes all handlers of all loggers of the Java util logger.
This cause a severe regression: all other applications in the same JVM as
Tomcat do not log anything anymore (since their handlers have disappeared).
Is this an expected behaviour? How do we tell Catalina to only remove the
handlers for the loggers by the Web application that is being undeployed?
For now, in the Tomcat integration in our application server, we have worked
around the problem by setting clearReferencesLogFactoryRelease to false. This
is of course a very bad workaround.
