DO NOT REPLY [Bug 52861] New: WebappClassLoader stopped too early in
webapp shutdown cycle
https://issues.apache.org/bugzilla/show_bug.cgi?id=52861
Bug #: 52861
Summary: WebappClassLoader stopped too early in webapp shutdown
cycle
Product: Tomcat 6
Version: 6.0.29
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: nrb@plusgrade.com
Classification: Unclassified
I have a webapp that fails on shutdown in the following code block from Spring
Framework's AbstractApplicationContext (spring-context-3.0.6.jar,
AbstractApplicationContext.java line 1013:)
// Stop all Lifecycle beans, to avoid delays during individual destruction.
try {
getLifecycleProcessor().onClose();
}
catch (Throwable ex) {
logger.warn("Exception thrown from LifecycleProcessor on context close",
ex);
}
What is happening is that the catch block is reached for whatever reason, and
then the call to "logger.warn()" fails with the following exception if the
webapp has not loaded these classes prior to being shut down:
SEVERE: Servlet X threw unload() exception
javax.servlet.ServletException: Servlet.destroy() for servlet offers threw
exception
[snip]
Caused by: java.lang.NoClassDefFoundError:
org/apache/log4j/spi/ThrowableInformation
I see the WebappClassloader implements Lifecycle and provides start()/stop()
methods and I assume that it has been stopped prior to invoking the web app's
shutdown listeners. If that is the case, it seems like this is the wrong order
for those two operations.

This looks like a configuration problem with ENABLE_CLEAR_REFERENCES although
since you haven't provided the full stack trace it is hard to be sure.
The users list is the place to seek help with this until that discussion
reaches the point where it is determined that there is actually a Tomcat bug
here.
