>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.4.7
>            Reporter: Graeme Rocher
>            Priority: Major
>             Fix For: 2.5.9, 3.0.0-rc-2
>
>          Time Spent: 1.5h
>  Remaining Estimate: 0h

> The following example:
> {code}
> class Foo {
>     Object propertyMissing(String name) {
>          return "stuff"
>     }
>     
>     void build(Closure callable) {
>          this.with(callable)
>     }
> }
> @groovy.transform.CompileStatic
> class Bar {
>     protected List bar = []
>     
>     boolean doStuff() {
>         Foo foo = new Foo()
>         foo.build {
>            return bar.isEmpty() 
>         }
>     }
> }
> new Bar().doStuff()
> {code}
> Produces 
> {code}
> java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
> 	at Bar$_doStuff_closure1.doCall(ConsoleScript3:19)
> 	at Bar$_doStuff_closure1.call(ConsoleScript3)
> 	at org.codehaus.groovy.runtime.DefaultGroovyMethods.with(DefaultGroovyMethods.java:242)
> 	at Bar.doStuff(ConsoleScript3:18)
> 	at Ba
> {code}
> The equivalent code without CompileStatic prints:
> {code}
> Result: false
> {code}
> The behaviour of both should be he same IMO
