>                 Key: GROOVY-7512
>                 URL: https://issues.apache.org/jira/browse/GROOVY-7512
>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler, Static compilation, Static Type Checker
>    Affects Versions: 2.4.4
>            Reporter: César Izurieta
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 4.0.0-alpha-1, 3.0.5
>
>          Time Spent: 0.5h
>  Remaining Estimate: 0h
>
> When running:
> {code:title=test.groovy|borderStyle=solid}
> class X {
>     Closure action = {}
> }
> trait T {
>     void say(String text) {
>         println text
>     }
>     @groovy.transform.CompileStatic
>     X getX() {
>         new X(action: {
>             say "Hello!"
>         })
>     }
> }
> class A implements T {
> }
> new A().x.action()
> {code}
> The following exception is thrown:
> {code}
> Caught: java.lang.ClassCastException: java.lang.Class cannot be cast to T
> java.lang.ClassCastException: java.lang.Class cannot be cast to T
> 	at T$Trait$Helper$_getX_closure1.doCall(test.groovy:14)
> 	at T$Trait$Helper$_getX_closure1.doCall(test.groovy)
> 	at test.run(test.groovy:23)
> {code}
> This is only happening on groovy 2.4.4. Removing the static compilation annotation or reverting to groovy version 2.4.3 makes the code work. 
> The commit that is causing this problem seems to be: 1bbed25aa3a08bc0cb7e14e49a1e7c2b82f21a26
