Description

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(); }

}
