[Bug classpath/23026] ObjectInputStream can't deserialize arrays from a Sun stream

This suggest that we check the serial version uid from a
ObjectStreamClass of an array Class object but should just ignore it.

Two experiments to consider:
- Is the array serial uid we get from the Sun side "stable"?
  Does it just give us something random or do we make some mistake in
  recalculating the uid?
- If we sent a clearly wrong (random) uid for an array Class does to Sun
  also fail? Is the other side really ignoring the uid, or is it being
  liberal in what it accepts?

Note that ObjectStreamClass.getClassUID() has some special code to
handle the array case already.

Also note that reflection on array classes is tricky. It might be a good
idea to try a more mature vm to check against. libgcj gets this right.
Arrays are always abstract, final, inherit the accessible flags of their
component type (or public when primitive) and are never an interface.
