DO NOT REPLY [Bug 48510] New: Memory leak after undeploying web application using custom log formatter

https://issues.apache.org/bugzilla/show_bug.cgi?id=48510

           Summary: Memory leak after undeploying web application using
                    custom log formatter
           Product: Tomcat 6
           Version: 6.0.20
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: dsavickas@gmail.com


Created an attachment (id=24819)
 --> (https://issues.apache.org/bugzilla/attachment.cgi?id=24819)
Zipped Maven project folder

After undeploying web application (see attachment) instance of CustomFormatter
is left non-reclaimed. As CustomFormatter is loaded by WebAppClassLoader, the
classloader remains in memory too.

To reproduce: deploy attached web application and stop/start it several times,
then do a heap dump. Check the dump using Eclipse Memory Analyzer or YourKit
Java Profiler and notice multiple WebAppClassLoaders present in the dump.

Issue seems to be related to org.apache.juli.ClassLoaderLogManager.
org.apache.juli.ClassLoaderLogManager$LogNode keeps a reference to
java.util.logging.Logger. Logger has a handler with CustomFormatter.

Thanks for the test case. This bug has the same root cause as bug 48421 so I am
marking it as a duplicate.
