It's implemented in bitcoinj's TransactionBroadcast class. Received
reject messages are collected and -- if a certain consensus (currently:
half of connected peers) is reached -- a RejectedTransactionException is
raised.
The handling of that exception in Bitcoin Wallet is extremely
rudimentary. I think it still only shows the exception message. But
certainly I was hoping to improve on this soon.
