Concurrent Modification exception while evicting cache in Hibernate

My application maintains a cache of list of users and it is evicted when any new user is created. I am getting Concurrent Modification exception while evicting the cache.

Stack trace :

    at com.mytestapp..webapp.controller.admin.SystemUserManagementController.saveSystemUserData(SystemUserManagementController.java:529)

In my controller the code is as follows :

systemUserProfileManager.saveSystemUserProfile(userBasicInfo); // async call
StartupListener.refreshContext(request.getSession().getServletContext()); // cache evict

refreshContextMethod in StartupListener :

public static void refreshContext(ServletContext context) {
        ApplicationContext ctx = WebApplicationContextUtils
                .getRequiredWebApplicationContext(context);
        MyCacheManager myCacheManager = (MyCacheManager) ctx
                .getBean(myCacheManager);
        
        LOG.debug("Processing started for refreshing Servlet Context/ Cache!");
        // RESET All Cache
        myCacheManager.resetTeamListCache();
        LOG.debug("Processing completed for refreshing Servlet Context/ Cache!");
    }

resetTeamListCache method in MyCacheManager :

@CacheEvict(value = CacheConstants.SALES_TEAM_LIST, allEntries = true)
public void resetTeamListCache() {
    // Intentionally blank
}
