Description

When making a call to the RPC relay to eth_getBlockByNumber or eth_getTransactionByHash, Web3J fails to serialize the Transaction class due to the 'v' legacy field being a non-nullable Long.
This may also apply in all cases looking at the JSON-RPC Ethereum docs

I've opened a PR changing this to '0x0' instead of null when mapping.
#917

Steps to reproduce

  1. Create a basic repo that uses web3j
  2. Run:
EthBlock ethBlock = web3j.ethGetBlockByNumber(
                DefaultBlockParameter.valueOf(blockNumber), true).send();
  1. It will throw a JsonMappingException (see below)

Additional context

ERROR net.consensys.eventeum.chain.service.strategy.AbstractBlockSubscriptionStrategy: onError - There was an error when processing a block, disposing blocksubscription (will be reinitialised)

Thanks for opening the issue @sergioaiobuilders
Our goal with the response was to adhere t the execution apis which states that v should be a unit: ^0x([1-9a-f]+[0-9a-f]*|0)$.

Seems like you're right and we missed this.
We'll review the PR which you were kind enough to open. :)
