>    Affects Versions: 2.4.5
>            Reporter: Natsuki Takanashi

> The following code gives {{GroovyCastException}}.
> {code}
> class Main {
>   public static void main(String... args) {
>     Test test = new Test()
>   }
> }
> @CompileStatic @Newify
> class Test {
>   private HashMap<String, A> hashMap = [:]
>   public Test() {
>     set()
>     test()
>   }
>   public void test() {
>     hashMap.each() { String string, A a ->
>       a.printString()
>     }
>   }
>   public void set() {
>     hashMap.put("aaa", B.new("xxx"))
>     hashMap.put("bbb", B.new("yyy"))
>   }
> }
> class A {
>   public String string = ""
>   public void printString() {
>     println(string)
>   }
> }
> class B extends A {
>   public B(String string) {
>     this.string = string
>   }
> }
> {code}
> The code below is a part of the decompiled {{Test.class}}. Groovy tries to cast {{this}} instead of {{a}}.
> {code}
> public Object doCall(String string, A a) {
>   ((A)ScriptBytecodeAdapter.castToType(((_test_closure1)this).getThisObject(), A.class)).printString();
>   return null;
> }
> {code}
> When {{@CompileStatic}} is omitted, or when {{@Newify}} is omitted and {{B.new}} is replaced by {{new B}}, the code above gives no exception and runs as expected.
