> For byte array backed message stores (i.e. LongByteArrayMessageStore,
> ByteArrayMessagesPerVertexMessageStore, and IntByteArrayMessageStore)
> currently, when the byte[] of underlying ExtendedDataOuput runs out of space
> (i.e. UnsafeByteArrayOutputStream) we see
> java.lang.NegativeArraySizeException in the SendWorkerMessagesRequest. We
> want to catch the exception dump the known vertex information and explain the
> issue (the amount of bytes sent to this vertex exceeded the max capacity
> of this ExtendedDataOutput). In this diff all ByteArray backed
> messagestores have been modified to behave as explained.
