           Summary: Classloader leak in
                    org.apache.tomcat.util.http.ServerCookie
           Product: Tomcat 5
           Version: 5.5.24
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: davide.romanini@gmail.com


I'm investigating problems related to PermGen saturation on hot redeploy of my 
web applications. Using jhat I found that the class 
org.apache.catalina.util.http.ServerCookie has a static reference to my webapp 
classloader through the log field. This is what jhat shows:

Static reference from org.apache.tomcat.util.http.ServerCookie.log (from class 
org.apache.tomcat.util.http.ServerCookie) :
--> org.apache.commons.logging.impl.Log4JLogger@0x66826ed8 (16 bytes) (??:)
--> class org.apache.commons.logging.impl.Log4JLogger (84 bytes) (??:)
--> org.apache.catalina.loader.WebappClassLoader@0x6632eb38 (152 bytes) 

It is similar to bug#42172.

The problem shows in Tomcat 5.5.25
