Can't catch exception between services in Grails - exception

Question

I'm trying to catch an exception between two services but the catch code is unreachable. Does any one knows why?
Controller:
def controllerMethod() {
try {
service1.execute()
} catch(CustomException ce) {
// unreachable code
}
}
Service 1:
def service2
def service1Method() {
try {
service2.execute()
} catch(CustomException ce) {
// unreachable code
throw ce
}
}
Service 2:
def service2Method() {
throw new CustomException("exception")
}
Exception:
class CustomException extends Exception {
CustomException(String message){
super(message)
}
}

See the project at github.com/jeffbrown/victorsoaresexception.
grails-app/services/victorsoaresexception/Service1Service.groovy
package victorsoaresexception
import grails.gorm.transactions.Transactional
#Transactional
class Service1Service {
Service2Service service2Service
def service1Method() {
try {
service2Service.service2Method()
} catch(CustomException ce) {
// unreachable code
throw ce
}
}
}
grails-app/services/victorsoaresexception/Service2Service.groovy
package victorsoaresexception
class Service2Service {
def service2Method() {
throw new CustomException("exception")
}
}
grails-app/controllers/victorsoaresexception/DemoController.groovy
package victorsoaresexception
class DemoController {
Service1Service service1Service
def controllerMethod() {
try {
service1Service.service1Method()
render "No Exception Was Thrown"
} catch(CustomException ce) {
render "CustomException was thrown, and caught by controller"
}
}
}
That all appears to work:
