> The code below fails with {{java.lang.ClassCastException: Test$_doStuff_closure1 cannot be cast to Test}}.  Interestingly, if I remove the {{@CompileStatic}} annotation or make the member variable non-private it works as expected.
> {code:java}
> class Test {
>     private String str = "hi"
>     @groovy.transform.CompileStatic
>     public void doStuff() {
>         Closure c = {
>             println str
>         }
>         c()        
>     }
> }
> new Test().doStuff()
> {code}
> It also works when {{@CompileStatic}} is moved up to the class level
> {code:java}
> @groovy.transform.CompileStatic
> class Test {
>     private String str = "hi"
>     public void doStuff() {
>         Closure c = {
>             println str
>         }
>         c()        
>     }
> }
> new Test().doStuff()
> {code}
