[jira] [Updated] (GROOVY-7758) GroovyCastException when both @CompileStatic and @Newify are used

["Yuki Goto (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-7758?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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 blow is a part of the decompiled {{Test.class}}. Groovy trys 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.

  was:
The code below 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 blow is a part of the decompiled {{Test.class}}. Groovy trys 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.
