Nils Kuhn commented on GROOVY-7295:
-----------------------------------

Seems that the following solution to expose i18n resource bundles to javascript code in a grails application doesn't work due to this bug :(

> It works with other classes, even Java (Integer for example):

> trait Extra {
>     String extra() { "I'm an extra method" }
> }
> class Something {
>     String doSomething() { 'Something' }
> }
> def s = new Something() as Extra;
> assert "I'm an extra method" == s.extra()
> assert 'Something' == s.doSomething()
> def i = new Integer(0) as Extra;
> assert "I'm an extra method" == i.extra()
> def conf = new ConfigSlurper().parse('some = 7')
> // Uncomment it and you are receive error:
> // def ss = conf as Extra
> /*
> java.lang.NoClassDefFoundError: Extra
>     at ConsoleScript24.run(ConsoleScript24:16)
> Caused by: java.lang.ClassNotFoundException: Extra
>     ... 1 more
