Shil Sinha commented on GROOVY-7758:
------------------------------------
This occurs because 'implicitThis' is not set correctly in Newify transformed
method calls. A simpler example:
{code}
class A {
String foo() { 'abc' }
}
@groovy.transform.CompileStatic
@groovy.lang.Newify
String test(A arg) {
Closure<String> cl = { A it -> it.foo() }
cl.call(arg)
}
assert test(new A()) == 'abc'
{code}
The above fails with the same error (and for the same reason) as the example in
the issue description.
> GroovyCastException when both @CompileStatic and @Newify are used

>
> Key: GROOVY-7758
> URL: https://issues.apache.org/jira/browse/GROOVY-7758
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> 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.
