Jexl advice
Jexl javabean property names
It is better to use the getter name than the property name. JEXL will throw an exception if there is a null and referring to it as property name.
For example, this will return null

ProvisioningGroup provisioningGroup = new ProvisioningGroup();
Map<String, Object> variableMap = new HashMap<String, Object>();
variableMap.put("provisioningGroup", provisioningGroup);
String result = GrouperUtil.substituteExpressionLanguage("${provisioningGroup.getName()}", variableMap, true, false, false);
System.out.println(result);
