Description
To analyse ArrayIndexOutOfBounds exceptions it's useful to know the length of the array accessed. Example for load from / store to array with illegal index: int[] a = new int[3]; a[7]; Message before: 7 Message now: Index 7 out of bounds for length 3 arraycopy() also reports ArrayIndexOutOfBoundsExceptions. Before, it did not report any context for the exception. Now it says: arraycopy: source index -17 out of bounds for boolean[10] arraycopy: destination index -18 out of bounds for byte[5] arraycopy: last source index 13 out of bounds for char[10] arraycopy: last destination index 7 out of bounds for object array[5] arraycopy: length -19 is negative It was agreed to spell "out of bounds" with hyphens if used as an adjective, else without, which is the case here.
