           Summary: Memory Leak: Tomcat files keep references to classes
                    loaded by WebappClassLoader
           Product: Tomcat 5
           Version: 5.5.9
          Platform: All
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: [EMAIL PROTECTED]


I am running Tomcat 5.5.15 on the latest J2SE 1.6 Mustang build 74. 

org.apache.tomcat.util.digester.Digester maintains references to commons-logging
log that gets loaded by WebappClassloader. See attached.

Thus, applications that put commons-logging.jar and log4.jar in their
WEB-INF/lib will not be GC'ed on reloads, undeploys, and stops. This is a severe
memory leak for developer's using Tomcat for development.

Please see the attachment from the YourKit Profiler that confirms this finding.

Note: it appears the last place in Tomcat's source code where this error occurs.
Once this is fixed, Tomcat will be fully "developer-friendly". :-)
