Apparent problem with all tags in a TLD if one of the tags has an invalid configuration

           Summary: Apparent problem with all tags in a TLD if one of the
                    tags has an invalid configuration
           Product: Tomcat 4
           Version: 4.1.3
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Jasper 2
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: prasad.subramanian@sun.com


Here is a case :
in a TLD - MyTLD.tld we have two tags:
<tag>
 <tag-class>foo</tag-class>
 <tei-class>fooTagExtraInfo</tei-class>

  <variable> .... </variable>
</tag>

<tag>
 <tag-class>bar</variable>
 

  <variable>... </variable>
</tag>

In case tag bar is accesed in a JSP , then a comilation error is thrown , that 
says:
