           Summary: Out of memory being caused by notFoundResources in
                    org.apache.catalina.loader.WebappClassLoader
           Product: Tomcat 6
           Version: 6.0.20
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Catalina
        AssignedTo: dev@tomcat.apache.org

Guys

Tomcat 6.0.20, java 1.6, linux x64

org.apache.catalina.loader.WebappClassLoader records every resource you asked
for that doesn't exist.

On our site we have alot of pages ( > 800,000 )
all of which are using struts2 with validation.
every hit means the validator does a request for a resource
actionName-validation.xml

This then gets cached in the WebappClassLoader
about line 249

    /**
     * The list of not found resources.
     */
    protected HashMap notFoundResources = new HashMap();

Can this be made into a weak hash map perchance ?

or something so that it won't invoke a out of memory.
I'm also looking at removing the validator from those urls
if anyone knows how to tell the validation interceptor that we don't use the
xml files
and ONLY use annotations then that would be great :)
