[ https://issues.apache.org/jira/browse/GROOVY-7758?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shil Sinha resolved GROOVY-7758.
--------------------------------
Resolution: Fixed
> 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
> Assignee: Shil Sinha
> Fix For: 2.4.7
>
>
> 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.
