Description

After upgrading groovy from 2.4.7 to 2.4.10 all classes using the `groovy.beans.ListenerList` annotation fail to compile.
The error message is:

Caught: BUG! exception in phase 'canonicalization' in source unit '/tmp/fsck/bug.groovy' ClassNode#getTypeClass for Event is called before the type class is set 
BUG! exception in phase 'canonicalization' in source unit '/tmp/fsck/bug.groovy' ClassNode#getTypeClass for Event is called before the type class is set 

Code to reproduce:

class Event {
}

interface EventListener {
        void doSomething(Event e)
}

class EventHandler {
        @groovy.beans.ListenerList
        List<EventListener> listeners
}

def eh = new EventHandler()
eh.addEventListener({ println it} as EventListener)
eh.fireDoSomething(new Event())

Complete steps:

% sdk u groovy 2.4.7

Using groovy version 2.4.7 in this shell.
% cat bug.groovy 
class Event {
}

interface EventListener {
        void doSomething(Event e)
}

class EventHandler {
        @groovy.beans.ListenerList
        List<EventListener> listeners
}

def eh = new EventHandler()
eh.addEventListener({ println it} as EventListener)
eh.fireDoSomething(new Event())
