Groovy Upgrade
Grails 2.5.1 ships with Groovy 2.4.4 which includes some changes in behavior that may affect some applications. The following JIRA issues describe the changes in behavior.
Change In JSON Behavior
Prior to 2.5.1 something like JSON.parse("{'myList':null}").myList would evaluate to JSONObject.Null because of an implementation leak. In 2.5.1 this has been fixed to evaluate to null.
