I tried to reproduce your exception with the following snippet:

<c:forEach begin="-1" end="1">
    <p>blah
</c:forEach>

However, I got a much clearer and more obvious exception trace on the Tomcat default error page:

org.apache.jasper.JasperException: An exception occurred processing JSP page /jsp.jsp at line 12

9: <body>
10:         
eleven: 
12: <c:forEach begin="-1" end="1">
13: <p>bla
14: </c:forEach>
15:
