Do open nodes have parents?

[o-alex]

DirectMsgNetty class - getHeaderSize() method - line 66
the method, I think wrongly assumes everyone has VodConfig.PM_NUM_PARENTS, but open nodes have no parents. I suspect there should be a check and add that to header size only if node is nated

This isn't a blocking issue, as getHeaderSize() is only used to pre-allocate the size of the Buffer in Netty. If the buffer is a bit larger for open nodes, it only means more memory has been allocated than needed for the object. That extra memory shouldnt be sent out with the packet - it shouldnt affect packet size.
