------------------------------
Summary: Unexpected static initialization order
Key: GROOVY-10721
URL: https://issues.apache.org/jira/browse/GROOVY-10721
Project: Groovy
Issue Type: Bug
Affects Versions: 4.0.4, 3.0.8
Environment: openjdk 11.0.12 2021-07-20
Reporter: Luk N
Hi, I've encountered a small issue - assignments to static fields and
executions of static blocks do not happen in the same order they do in Java.
I'm not sure if they should, hence the ticket. In Java the assignments and
executions are in the declaration order, while Groovy seems to initialize
fields first. Attached sample java class, executable in groovy too.

import java.util.*;
class ListSupplier{
public static List getList(){
System.out.println("Getting list");
return new ArrayList<>();
}
}
class ListThenStatic{
static final List list = ListSupplier.getList();
static{
System.out.println("Static block");
}
}
class StaticThenList{
static{
System.out.println("Static block");
}
static final List list = ListSupplier.getList();
}
class Test {
public static void main(String[] args) {
ListThenStatic listThenStatic = new ListThenStatic();
StaticThenList staticThenList = new StaticThenList();
}
}{noformat}
Java produces output:
# Getting list
# Static block
# Static block
# Getting list
>From Groovy:
# Getting list
# Static block
# Getting list
# Static block
Is this behaviour expected and/or documented anywhere?
