Subject DO NOT REPLY [Bug 45745] New: memory leak after SecurityException from HostConfig.deployDescriptor
Date Thu, 04 Sep 2008 15:02:59 GMT
https://issues.apache.org/bugzilla/show_bug.cgi?id=45745

           Summary: memory leak after SecurityException from
                    HostConfig.deployDescriptor
           Product: Tomcat 6
           Version: 6.0.16
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: martin.schulz@emergis.com


Configure an invalid Context - e.g. with InvokerServlet yet unprivileged.

This generates the following exception:
Sep 2, 2008 5:26:57 PM org.apache.catalina.startup.HostConfig deployDescriptor
SEVERE: Error deploying configuration descriptor vOacisHelp.xml
java.lang.SecurityException: Servlet of class

Result:  memory leak by repeated attempts to to deploy the Context.

Jprofiler clearly shows that the ContextBindings hold on to all the repeatedly
created ApplicationContexts even though the Context wasn't successfully
deployed.

You might argue that this is an avoidable scenario, but I suspect that the
Exception handling isn't quite right here.
