you can put in a conditional to see if request.getParameter("chkbox") equals null.

The call to request.getParameterValues("chkbox") should be returning
null, not throwing an exception.
Anyway, if you want to make sure you have a non-null array with 0 or
more elements, you could write a scriptlet like:
%
String[] chkboxes;
if( request.getParameter("chkbox") == null ) {
