Thanks for your reply, please find the below code
In AdminGovController:

package com.acp.gov.schemas.controller;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.acp.gov.schemas.entity.NewUserEntity;
import com.acp.gov.schemas.form.NewUserForm;
import com.acp.gov.schemas.service.AdminService;
import com.cms.admin.exceptions.CMSServiceException;

@Controller
public class AdminGovController {
	
	@Autowired
	private AdminService adminService;

@RequestMapping("viewGovUser")
public ModelAndView getUserView(final NewUserForm newUser, final BindingResult result,
          final HttpServletRequest request){
List<NewUserEntity> list=null;
ModelAndView mav=new ModelAndView("viewGovUserList");
   try {
list=adminService.getAdminDetails();
} catch (CMSServiceException e) {
  e.printStackTrace();
}  
mav.addObject("list", list);

Adminservice.getadmindetails is returning odd number of elements. So inside your loop, the second call to next is trying to read beyond the last element
