I've had a look at the JLS to find out about the more or less special
case of a 2-dimensional array, whose first(outer) dimension is 0, but
I didn't find any extra mention of that case.

From what I read, it would evaluate *all* the dimensions, then check
if any of them is negative.  

But if first dimension is 0, then the loop shown in the "equivalent as"-
code sample would not get its body run even once, so actually it wouldn't
even notice if any of the further dimensions was negative.

What would be an accurate *purely JLS-based* prediction for
  new long[0][-1]
(not caring about actual existing JVM implementations) ?

PS: this is not a real problem for me, just curiosity.
