Eric Milles updated GROOVY-1092:
--------------------------------
Labels: ClassFormatError (was: )
> Multidimensional arrays are broken
> ----------------------------------
>
> Key: GROOVY-1092
> URL: https://issues.apache.org/jira/browse/GROOVY-1092
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 1.0-JSR-3
> Environment: Java 1.4.2, Windows XP
> Reporter: Peter Eastman
> Assignee: Jochen Theodorou
> Priority: Critical
> Labels: ClassFormatError
>
> Multidimensional arrays are completely broken. If I try to create one using
> the standard syntax
> a = new Object[2][2];
> I get an error
> Script1.groovy: 1: Unknown type: ARRAY_DECLARATOR at line: 1 column: 15.
> File: Script1.groovy @ line 1, column 15.
> Nor does there seem to be any other syntax for creating a multidimensional
> array. Of course, I can do it by using reflection:
> import java.lang.reflect.*;
> a = Array.newInstance(Object.class, (int []) [2, 2]);
> That successfully creates a multidimensional array, but as soon as I try to
> do anything with it, the parser dies. For example, a simple reference to
> a.length produces the following exception:
> java.lang.ClassFormatError: gjdk/[Ljava/lang/Object;_GroovyReflectorArray
> (Illegal Class name "gjdk/[Ljava/lang/Object;_GroovyReflectorArray")

> Passing the array as an argument to any method similarly produces an
> exception. This makes Groovy completely incapable of invoking any method
> that takes a multidimensional array as an argument.
