This code worked with the alpha1 compiler, but doesn't with alpha2.

> 1 class foo {
> 2 boolean b[][];
> 3
> 4 foo() {
> 5 b = new boolean[10][];
> 6
> 7 for (int i=0; i<10; i++)
> 8 b[i] = new boolean[2];
> 9 }
> 10
> 11 public static void main(String args[]) {
> 12 foo f = new foo();
> 13 System.out.println("Ok");
> 14 }
> 15 }

Rutime error message:

> Exception in thread "main" java.lang.IncompatibleTypeException
