Eric Milles updated GROOVY-896:
-------------------------------
Labels: ClassFormatError (was: )
> Problem when accessing arrays of arrays from groovy
> ---------------------------------------------------
>
> Key: GROOVY-896
> URL: https://issues.apache.org/jira/browse/GROOVY-896
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 1.0-JSR-2
> Environment: Windows, Java 1.5.0_03
> Reporter: Martin C. Martin
> Assignee: Jochen Theodorou
> Priority: Major
> Labels: ClassFormatError
> Fix For: 1.0-JSR-5
>
>
> If I create a Java class which contains a field declared as:
> int[][] x;
> then pass an object to groovy and ask it to execute:
> println (the object).x[0]
> it throws:
> Exception in thread "main" java.lang.ClassFormatError: Illegal class name
> "gjdk/[I_GroovyReflectorArray" in class file gjdk/[I_GroovyReflectorArray
> Printing just (the object).x works fine.
> The full code which reproduces this error is:
> bug4.groovy:
> class bug4 {
> def bubbles(a) {
> println a.x[0];
> }
> }
> bug4j.java:
> import groovy.lang.*;
> import java.io.*;
> import org.codehaus.groovy.control.CompilationFailedException;
> public class bug4j {
> public int[][] x;
>
> void ricky() throws CompilationFailedException, InstantiationException,
> IOException, IllegalAccessException {
> x = new int[][] {new int[5], new int[4], new int[3]};
>
> // Create the groovy object
> ClassLoader parent = getClass().getClassLoader();
> GroovyClassLoader loader = new GroovyClassLoader(parent);
> Class groovyClass = loader.parseClass(new File("bug4.groovy"));
> GroovyObject bug4 = (GroovyObject) groovyClass.newInstance();
> Object[] args = {this};
> bug4.invokeMethod("bubbles", args);
> }
> public static void main(String[] args) throws
> CompilationFailedException,
> InstantiationException, IOException, IllegalAccessException {
> (new bug4j()).ricky();
> }
> }
