[12] 8206403: ByteArrayOutputStream hugeCapacity method can return invalid capacity

[Brian Burkhalter]

https://bugs.openjdk.java.net/browse/JDK-8206403
http://cr.openjdk.java.net/~bpb/8206403/webrev.00/

Disallow creating an internal array of size larger than Integer.MAX_VALUE - 8.

The change if approved as-is will require a CSR for the @implNote.

Thanks,

Brian
