Description

The simplest class definition to reproduce this error:

class Bug {
String x = ""

static void main(args)

{ x = 13 }

}

Trying to run groovy on this:

$ groovy Bug.groovy

Exception in thread "main" java.lang.VerifyError: (class: Bug, method: main signature: ([Ljava/lang/String;)V) Incompatible type for getting or setting field

If I change the x = 13 to some variable name different than "x", it works. It seems that the local variable defined in the static method is clashing with the non-static class property.
