Fwd: Groovy Bug?
Hi,
Someone sent me the following email, showing a problem, which triggers an
interesting error message:
"This method should not have been called."
Coming from here:

Subject: Groovy Bug?
Hello,
I am playing around with groovy and the map data type I then added the
CompileStatic annotation and I got the following result. Since I have no
deep knowledge of Groovy I can't judge what this means but since groovy
mentions I should issue a bug. I have not done this via jira since I don't
have an account there, but I think it is fair to inform you about this.

Yeah, the thing is we shouldn't be showing that message: either we raise an
error, or it's type checked properly.

Removing the @TypeChecked line will achieve what they want - should
probably be raised as an error though.
