Grails requires restart after changes in domain class

Grails officially supports domain class reloading since version 2, but recently I found problems using it together with MongoDB GORM plugin, because it required application restart after every change to domain class.
So if Hibernate is primary GORM and Mongo is used only for some particular cases, disabling it can be a good option to make development easier.

Adding common methods to Grails domain objects

If you don't want to change your domain hierarchy, but need to add common function to multiple domains without copy/paste, one simple option is to create and implement trait. For example:
class Test implements LogTrait {
  String name

trait LogTrait {
  def springSecurityService

  def afterInsert() { as JSON)
Nice bonus is that events and injected services work just fine as it would be in original class.
