Description

Example from the mailing list

import groovy.mock.interceptor.StubFor

class Speaker {
   String name
   def startLecture() { "Starting..." }
}

def speakerStub = new StubFor(Speaker)
speakerStub.demand.startLecture() { "Intercepted!" }
def speaker1 = new Speaker()
speakerStub.use {
   def speaker2 = new Speaker()
   assert speaker1.startLecture() == "Starting..." // I would have expected "Intercepted!" here
   assert speaker2.startLecture() == "Intercepted!"
} 

Dierk's answer:
MockFor and StubFor work by replacing the MetaClass with a ProxyMetaClass
and therefore should not be dependend on whether you instantiate the
object before or inside the use closure.
If they do, it's a bug (maybe introduced by the latest changes to
the MOP impl). Please raise an issue.

I'm flagging this as a blocker because it is MetaClass related and we're on crunch mode.
