> I'm trying to generate the following code use BCEL:
> package bci;
> public class Test {
>   public int[] getArray() {
>     return new int[1];
>   }
>   public static void main(String[] args) {
>   }
> }
> I use BCELIfier to generate the code that creates Test. The snippet that creates getArray is
>   private void createMethod_2() {
>     InstructionList il = new InstructionList();
>     MethodGen method = new MethodGen(ACC_PUBLIC, new ArrayType(T_INT, 1), Type.NO_ARGS, new 
> String[] {  }, "getArray", "bci.Test", il, _cp);
>     InstructionHandle ih_0 = il.append(new PUSH(_cp, 1));
>     il.append(_factory.createNewArray(new ArrayType(T_INT, 1), (short) 1));
>     InstructionHandle ih_3 = il.append(_factory.createReturn(Type.OBJECT));
>     method.setMaxStack();
>     method.setMaxLocals();
>     _cg.addMethod(method.getMethod());
>     il.dispose();
>   }
> I run TestCreator (generated by BCELIfier) and execute Test, which triggers the following error:
> Exception in thread "main" java.lang.VerifyError: (class: bci/Test, method: getArray signature: ()[I) 
> Wrong return type in function
> If I return null rather than the array, everything is perfectly allright.
