Build Identifier: 20100617-1415

This is a regression since Helios, it worked correctly in former versions.

The following code illustrates the problem :

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<body>
<!-- OK -->
<a href="<c:url value="/my_url.do" />">My link</a>

<!-- OK -->
<a href="<c:url value="/my_url.do"><c:param name="myparam" value="${myValue}"></c:param></c:url>">My link</a>

<!-- JSP error -->
<a href="<c:url value="/my_url.do"><c:param name="myparam" value="${myValue}" /></c:url>">My link</a>
</body>
</html>


Reproducible: Always

Steps to Reproduce:
1. Create a basic webapp.
2. Paste the code above in a JSP file.
3. Check the « Problems » window, there is a JSP error with an empty message.
