Description

The following code works fine in 2.5.6 but breaks in 2.5.7:

import groovy.transform.CompileStatic

@CompileStatic
class Class1 {
    public String prop1
}

@CompileStatic
class Class2 {

    String doThing(Class1 c1) {
        return 'something'.with {
            println c1.prop1
            return it
        }
    }
}

new Class2().doThing(new Class1(prop1: 'value1'))

The error is

Access to Class1#c1 is forbidden at line: -1, column: -1

Note that if you remove the `public` modifier from `Class1.prop1` the code is fine. Likewise, if you take `@CompileStatic` off of `Class2`, everything works fine.
