Incompatible type for getting or setting field

[Alex Anderson]

Is there something obviously wrong with the following:

41 static Exchange mockExchange(body, Map headers) {
42 Exchange x = Mock()
43 def out = Mock(Message)
44 if(body) out.body >> body
45 out.headers >> headers
46 x.out >> out
47 return x
48 }


Gives the following exception:

| Error Error executing script TestApp: (class:
frontlinesms2/WebConnectionServiceSpec, method: mockExchange
signature: (Ljava/lang/Object;Ljava/util/Map;)Lorg/apache/camel/Exchange;)
Incompatible type for getting or setting field (NOTE: Stack trace has

Removing `static` seems to fix it...

Mocks can't be used in static context. Not nice that it gives a VerifyError, though. Mind to file an issue?

Cheers,

Done: https://code.google.com/p/spock/issues/detail?id=270

And thanks for the clarification :¬)
