IllegalArgumentException when using context-param in web.xml

           Summary: IllegalArgumentException when using context-param in
                    web.xml
           Product: Tomcat 5
           Version: Nightly Build
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: cheng.fang@sun.com


It appears any wars with context-param failed to
deploy.  When parsing web.xml, context-param elements are parsed and added
to map twice for some reason, and thus cause the second adding to throw
IllegalArgumentException.

I instrumented
apache/jakarta-tomcat-
catalina/catalina/src/share/org/apache/catalina/core/StandardContext.java
addParameter method

Here it shows context-param was added twice:

INFO: Installing web application at context path /jsp-examples from URL
file:/.../jakarta-tomcat-5/webapps/jsp-examples
### name=webmaster value=myaddress@mycompany.com
### map={}
### value=null
### to add ok
### name=webmaster value=myaddress@mycompany.com
### map={webmaster=myaddress@mycompany.com}
### value=myaddress@mycompany.com
### to throw

To repruduce it, just add to jsp-examples/web-inf/web.xml:

    <context-param>
      <param-name>webmaster</param-name>
      <param-value>myaddress@mycompany.com</param-value>
      <description>
        The EMAIL address of the administrator to whom questions
        and comments about this application should be addressed.
      </description>
    </context-param>
