      Description

      When running this unit test:

          @Test
          public void testAllDelineatedValuesCount() {
              final Map<String, String> attributes = new HashMap<>();
      
              final String query = "${allDelineatedValues('${test}', '/'):count()}";
      
              attributes.put("test", "/");
              assertEquals(ResultType.WHOLE_NUMBER, Query.getResultType(query));
              assertEquals("0", Query.evaluateExpressions(query, attributes, null));
          }
      

      This will throw:
