           Summary: Broken jsp shows random errors
           Product: Tomcat 5
           Version: 5.5.8
          Platform: PC
               URL: http://www.dmdinfo.org/indexbad.jsp
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: dino@felstar.com


Try the above URL in IE or firefox, refresh repeatedly.

I can replicate this for 5.5.0, 5.5.5, 5.5.8, 5.5.9, i.e. all 5.5.x I've tried.

This does not happen for 5.0.30

If I do an out of the box tomcat 5.5.8 install.

Goto webapps/ROOT

copy index.jsp to index2.jsp

break index2.jsp, e.g. <%@ !page session="false" %>


start tomcat

put index2.jsp in the browser (IE)


I get an expected 500 error but if I refresh I sometimes get a comile error.
It seems to switch randomly.

e.g.

org.apache.jasper.JasperException: Unable to load class for JSP
org.apache.jasper.JspCompilationContext.load(JspCompilationContext.java:591)
