Description

The following script throws StackOverfloeError on the last line:

class SampleA {
public void foo()

{ println 'Original foo ' + receive('') }

protected Object receive()

{ return "Message" }

protected Object receive(Object param)

{ receive() + param }

}

class SampleB {}

SampleB.metaClass {
mixin SampleA

foo = {->
println 'New foo ' + receive('')
}
}

final SampleA a = new SampleA()
a.foo()

final SampleB b = new SampleB()
b.foo()

Basically I'm trying to mix-in the SampleA functionality into SampleB and override the SampleA.foo() behavior at the same time. It works until I try to call the receive(String) method, which calls the receive(void) method in turn.
