Hi ,
While upgrading from tomcat 8.0.18 to tomcat 8.0.30 version ,we are facing
the below issue .The displaytag version used by the application is
DisplayTag 1.1
Caused by: javax.servlet.ServletException: javax.servlet.jsp.JspException:

What i could understand is application is throwing exception due to change
in the getParameter method of ApplicationHttpRequest class ,which earlier
was accepting all datatypes (like Integer)
is now restricted to 'String' datatype only .
Kindly let me know why this change has been done ( in the getParameter
method of ApplicationHttpRequest class) and the suggest me the path forward
for fixing the issue.
Thanks & Regards,
