ExpandoMetaClass.enableGlobally()

Object[] myObjectArray = ['a', 'b'] as Object[]

closure = {
	println 'closure running...'
}
	
closure(myObjectArray)

I have tested with versions all the way back to 1.7.0 and the exception is thrown for all the versions I tested.

If I remove the ExpandoMetaClass.enableGlobally(), the exception goes away.

I think this is related to http://jira.grails.org/browse/GRAILS-8002, though I am not sure why that problem just showed up in Grails 2.0-M2. I have not been able to reproduce it with Grails 1.3.7.
