VerifyError when nesting tags

           Summary: VerifyError when nesting tags
           Product: Tomcat 4
           Version: 4.0.1 Final
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: ericzbeard@hotmail.com


I have a set of fairly simple nested tags that are generating a VerifyError 
when I try to use them in a jsp.  The problem does not happen with the same 
setup on a linux box, only with Solaris 8 and jdk 1.3 or 1.4

Here's the error: (the only difference between this one and the jdk 1.3 error 
is the Class.x methods)
