I think the transient field do not need to serialize. but it want to serialize now.
Some services which in domain-classes do not need to save in mongodb, but it will save now.
example:
I use spring-security-core, the Person.groovy has springSecurityService field, and I give transient on it, but when I use myperson.save(), the message "Message: can't serialize class grails.plugins.springsecurity.SpringSecurityService" will be there.

I create a test app, grails test-app can see the exception.
