> Key: GROOVY-6610
> URL: https://issues.apache.org/jira/browse/GROOVY-6610
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.2.2, 2.4.0-rc-1
> Environment: GNU/Linux (x64 SUSE and x86 Fedora Core 18)
> Reporter: David Costanzo
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 3.0.8, 4.0.0-alpha-3
>
> Attachments: ReproBug.groovy
>
>
> The attached script causes the following syntax error when run with Groovy
> 2.2.2.
> {quote}
> Caught: java.lang.VerifyError: (class: ReproBug$MyClass, method: <init>
> signature: ()V) Expecting to find object/array on stack
> java.lang.VerifyError: (class: ReproBug$MyClass, method: <init> signature:
> ()V) Expecting to find object/array on stack
> at ReproBug.main(ReproBug.groovy:18)
> {quote}
> The code compiles and runs fine as a Java class, which is why I think this is
> a bug in Groovy.
> The problem requires the conjunction of two things:
> 1) A constructor that invokes another constructor
> 2) Converting an integer to a string as a parameter to the constructor
> I encountered this during real-world scripting (although I used a integer
> literal), but was able to figure out the cause and work-around the problem.
> As such, this does not personally impact me; I am reporting it because I like
> Groovy and this is an easy way to contribute.
> Since I don't know whether you prefer an attachment or an inline quote, here
> is the code.
> {code}
> public class ReproBug {
> static private Integer MYINT = 4;
>
> private static class MyClass {
> public final String value;
> public MyClass(String string) {
> value = string;
> }
> public MyClass() {
> this(MYINT.toString()); // <--- causes problems
> }
> }
> public static void main(String[] args) {
> System.out.println(new MyClass().value);
> }
> }
> {code}
> I haven't figured out how to create a Groovy unit test case. If someone can
> point me to an example where simply getting the script to compile is proof
> that the bug is fixed, I'll try to work the attached code into a Groovy unit
> test case.
