Grails "checked" exception

Question

I need to throw exception from Grails service. But :

The exception has to be "checked" so that Hibernate would not rollback upon throwing that exception. But looks like the base exception class in Grails ( "GrailsException" ) is unchecked (extented from RuntimeException). Is there any checked exception exists in Grails that I can extend for my purpose? If not how can I create a checked exception class in Grails?
I am not very clear about when an exception can be called "checked" or "unchecked"? May be, more specifically, my question is what is a checked exception and what are the characteristics of it?

I can provide code example if more clarification on my question is required. I tried:

class MyException extends GrailsException { 
}

and it's rolling back the transaction on this exception

Thanks in advance

There's no requirement that you subclass any Grails exception - extend java.lang.Exception or any other checked exception as your base class.
