This error is related to a bug reported in bugs.sun.com/bugdatabase/view_bug.do?bug_id=4337052, which stated:
The problem is that a JSP custom tag was specified with
a String expression in the attribute value as: attname="<%= ..."StringValue" %>" using
double quotes to delimit the attribute value expression as well as a String within the expression.
The JSP parser doesn't like this.
The way around this is to use single quotes to delimit the attribute value:
attname='<%= ..."StringValue" %>'
