Abstract
When a Bridge method with no return value is called from a smart contract it causes the node to throw a null pointer exception and the transaction to be reverted. This RSKIP proposes a change so that no exception is thrown and the transaction is not reverted.
Motivation
There are currently 6 Bridge methods that have no return value.
- addSignature
- receiveHeaders
- registerBtcCoinbaseTransaction
- registerBtcTransaction
- releaseBtc
- updateCollections
If any of these methods were to be called from a smart contract, the transaction would get automatically reverted.
Specification
When the Bridge executes a method that has no return value, return an empty byte array instead of null.
