>                 URL: https://issues.apache.org/jira/browse/GROOVY-10902
>             Project: Groovy
>          Issue Type: Bug
>          Components: Stub generator / Joint compiler
>    Affects Versions: 3.0.14, 4.0.7
>            Reporter: Onni Koskinen
>            Assignee: Eric Milles
>            Priority: Major

> If we define a constant that is resolved during runtime in a Groovy class and reference it in a Java class, it's value gets a static default value in the Java class. This seems to be a regression in Groovy 3.0.10 as earlier versions don't have the problem. Also affects all 4.0.x versions that I tested.
> Example:
> {code:groovy}
> // G.groovy
> class G {
>     public static final int DYNAMIC_CONSTANT = (9.9).intValue()
> } {code}
> {code:java}
> // J.java
> public class J {
>     public static void main(String[] args) {
>         System.out.println(G.DYNAMIC_CONSTANT);
>     }
> } {code}
> *Groovy 4.0.7*
> Prints 0 with the following bytecode for J#main
> {code:java}
> 0: getstatic     #2 // Field java/lang/System.out:Ljava/io/PrintStream;
> 3: iconst_0
> 4: invokevirtual #4 // Method java/io/PrintStream.println:(I)V
> 7: return{code}
> *Groovy 3.0.9*
> Correctly prints 9 with the following bytecode:
> {code:java}
> 0: getstatic     #2 // Field java/lang/System.out:Ljava/io/PrintStream;
> 3: getstatic     #3 // Field G.DYNAMIC_CONSTANT:I
> 6: invokevirtual #4 // Method java/io/PrintStream.println:(I)V
> 9: return {code}
