Description

I was surprised by the following behavior:

class Person {
    Object invokeMethod(String name, Object args) {
        return false
    }
}

def person1 = new Person()

Person.metaClass.newMethod = { ->
   return true
}

assert new Person().newMethod()
assert person1.newMethod()

The last assert only works, if I set ExpandoMetaClass.enableGlobally() at the beginning of the script

The javadoc of enableGlobally says:

Call to enable global use of global use of ExpandoMetaClass within the registry. This has the advantage that inheritance will function correctly, but has a higher memory usage on the JVM than normal Groovy

The above use case should be added to the javadoc.

I guess with Groovy 2.0 things will become more intuitive anyway
