Don't work with parity 1.4.9 after ETC DieHard Fork about web3j

[conor10]

Fixed in v1.1.2.

[conor10]

What value are you seeing in the JSON-RPC transaction receipt object in the "v" field? This should be a byte value encoded as a string (Geth) or byte (Parity). I'm thinking ETC is providing a non-byte value here.

See ethereum/EIPs#155 for further information. A dump of the JSON-RPC objects is fine.

In order to display the HTTP requests/response, please see https://web3j.github.io/web3j/trouble.html#i-want-to-see-details-of-the-json-rpc-requests-and-responses

I use Parity 1.4.9

ChainID for Ethereum Classic is 0x3d

I suppose it may be issue with java byte type which you used for v field in tx

[conor10]

Yes, but it looks like some of those chain id's are coming through with 0x9d which is a somewhat larger value.

[gagarin55]

So, how we can solve it? Otherwise web3j is incompatible with Ethereum Classic :(

[splix]

@conor10 (0x9d - 35) / 2 == 61, so 0x9d is a correct v value for unprotected tx on chain with id 61

[splix]

@conor10 see here ethereum/EIPs#155

If block.number >= FORK_BLKNUM and v = CHAIN_ID * 2 + 35 or v = CHAIN_ID * 2 + 36

With CHAIN_ID equal to 61 you have:

v = 61 * 2 + 35 == 157 == 0x9d

[conor10]

Yes - I'll change to an int for the next release.
