Yuki Goto updated GROOVY-7758:
------------------------------
Description:
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.
