The
votersfield within theVoterSetis final an initialized within the constructor only and never changes.The
voterKeys()method is called several times and it always computes the mapping and the collection from thevotersfield on each call creating stream overhead and allocating a new HashSet. Unless I am missing anything it seems to be useless.This PR changes such behaviour computing an immutable HashSet
voterKeysone time in the constructor.
