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: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
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
org.apache.catalina.servlets.InvokerServlet is privileged and cannot be loaded

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.
