EDIT

should be fully fixed.

before closing disable in eu.etaxonomy.dataportal.pages.PortalPage.pageHealthChecks() :

        try {
            String ignore_error = "Expecting web service to return pager objects but received an array";
            List<String> errors = getErrors().stream().filter(str -> str.startsWith(ignore_error)).collect(Collectors.toList());
            assertTrue("The page must not show an error box", errors.size() == 0);
        } catch (NoSuchElementException e) {
            //IGNORE since this is expected!
        }

and run the tests : http://int.e-taxonomy.eu/jenkins/job/drupal7-cdm_dataportal-SNAPSHOT/

exception handling in PortalPage.pageHealthChecks() is removed and all test are still running successfully.
