[Dúvida] ORA-00001: restrição exclusiva

Eu to fazendo um programa que cria personagens de RPG como estudo, mas na hora de inserir eles no banco de dado ta dando esse erro "ORA-00001: restrição exclusiva". Pelo que eu pesquisei esse erro acusa que eu estou tentando dar um insert com uma chave que já existe, mas a chave primária dos objetos que eu tô colocando são diferentes.

Eu fiz o seguinte: Primeiro fiz o insert com os 4 players e deu certo, tão os 4 salvos no banco de dados, mas aí na hora do insert dos characters, só o c4 foi incluso, os outros 3 deram esse erro.

método na classe CharacterDAO:

public void includeChar(Character character) {

        conexao = GerenciadorBD.obterConexao();
        PreparedStatement comandoSQL = null;


        try {
            comandoSQL = conexao.prepareStatement("insert into CHARACTER(IDCHAR, CHARNAME, STRENGHT, INTELIGENCE, LUCK,"
                    + "CHARISMA, HPPOINTS, ARMOR, PLAYER, CHARRACE, SPEED, CHARLEVEL)values(?,?,?,?,?,?,?,?,?,?,?,?)");
            comandoSQL.setInt(1, character.getCharId());
            comandoSQL.setString(2, character.getCharName());
            comandoSQL.setInt(3, character.getStrenght());
            comandoSQL.setInt(4, character.getInteligence());
            comandoSQL.setInt(5, character.getLuck());
            comandoSQL.setInt(6, character.getCharisma());
            comandoSQL.setInt(7, character.getHp());
            comandoSQL.setInt(8, character.getArmor());
            comandoSQL.setInt(9, character.getPlayer().getPlayerId());
            comandoSQL.setString(10, character.getCharRace().toString());
            comandoSQL.setInt(11, character.getSpeed());
            comandoSQL.setInt(12, character.getLevel());

            comandoSQL.executeUpdate();
            conexao.close();
            comandoSQL.close();

        } catch (SQLException e) {
            e.printStackTrace();
        }

    }
