getopts of Perl is not working Tomcat 9

[Jonnalagadda, Swathi (External)]

Hi 

We have our web application implemented in Perl cgi which is using below 
function of perl. we are upgrading from Tomcat 8.0.21 to Tomcat 9.0.38. 

The below function (getopts) is working fine Tomcat 8.0.21 but is not working 
in Tomcat 9.0.38. We even tried Tomcat 9.0.39 as well and it is not working 
even in 9.0.39.

use Getopt::Std;

getopts('ei:npXP');

Could you please suggest a solution here.

Thanks
Swathi
