Description

def a = new Dummy()
//def a = new Object()
Closure cl = {a.foo()}

a.metaClass.foo {println "Original version"}
cl(1.5G)

a.metaClass.foo {println "Updated version"}
cl(1.5G)

class Dummy {}
This issue imposes some problems on GPars DynamicDispatchActors:

This script outputs:
Original version
Original version

while I would expect
Original version
Updated version

Additionally, the behavior differs depending on whether "a" is an instance of a Java or a Groovy class. After making "a" an instance of a Java class, I get the expected output.
