Daniel Sun commented on GROOVY-9288:
------------------------------------

The same code fails in 3.0.0-rc-1 too: 
{{Access to a.Abstract_Class#protectedField is forbidden at line: 13, column: 24}}

>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 2.5.7, 2.5.8
>            Reporter: John Bellassai
>            Priority: Major
>
> The following code works fine in 2.5.6 but breaks in 2.5.7 and 2.5.8:
> {code:java}
> GroovyShell shell = new GroovyShell()
> shell.evaluate('''
>     package a
>     
>     import groovy.transform.CompileStatic
>     
>     @CompileStatic
>     abstract class Abstract_Class {
>         protected String protectedField = 'field'
>         
>         abstract String doThing()
>     }
>     assert true''')
> shell.evaluate('''
>     package b
>     
>     import a.Abstract_Class
>     import groovy.transform.CompileStatic
>     
>     @CompileStatic
>     class ConcreteClass extends Abstract_Class {
>        
>         @Override
>         String doThing() {
>             'something'.with {
>                 return protectedField
>             }
>         }
>     }
>     assert true''')
> shell.evaluate("assert new b.ConcreteClass().doThing() == 'field'")
> {code}
> {noformat}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Script2.groovy: 13: Access to a.Abstract_Class#protectedField is forbidden @ line 13, column 32.
>                            return protectedField
>                                   ^
> {noformat}
> If you change both classes to be in the same package, you get a runtime error like this:
> {noformat}
> tried to access field a.Abstract_Class.protectedField from class a.ConcreteClass$_doThing_closure1
> java.lang.IllegalAccessError: tried to access field a.Abstract_Class.protectedField from class a.ConcreteClass$_doThing_closure1
> {noformat}
