           Summary: Classloader leak caused by request recycle
           Product: Tomcat 5
           Version: 5.5.17
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: [EMAIL PROTECTED]


It seems that a classloader leak is caused by the re-use of a request object
when connecting to tomcat. Just after a connection attempt to my servlet and a
undeploy/redeploy procedure, my classloader won't go because of the reference
displayed below (collected with hat):

--> [EMAIL PROTECTED] (field filterChain:)

   --> [EMAIL PROTECTED] (field context:)
    --> [EMAIL PROTECTED] (field loader:)
     --> [EMAIL PROTECTED] (field parentClassLoader:)
      --> [EMAIL PROTECTED] (field parent:)
       --> [EMAIL PROTECTED]


Then I modified the recycle method of org.apache.catalina.connector.Request
while adding filterChain=null (which was missing) and my classloader was
correctly garbaged. I guess the filterChain variable must be nullified.
