Pessoal,

No meu caso o problema estava na classe LancesLeilaoActivity,

package br.com.alura.leilao.ui.activity;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

import java.io.Serializable;

import br.com.alura.leilao.R;
import br.com.alura.leilao.model.Leilao;

public class LancesLeilaoActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_lances_leilao);
        Intent dadosRecebidos = getIntent();
        if(dadosRecebidos.hasExtra("leilao")){
            Leilao leilao = (Leilao) dadosRecebidos.getSerializableExtra("leilao");
            TextView descricao = findViewById(R.id.lances_leilao_descricao);
            descricao.setText(leilao.getDescricao());
            TextView maiorLance = findViewById(R.id.lances_leilao_maiores_lances);
            maiorLance.setText(String.valueOf(leilao.getMaiorLance()));
            TextView menorLance = findViewById(R.id.lances_leilao_menor_lance);
            menorLance.setText(String.valueOf(leilao.getMenorLance()));
        }
    }
}

A referencia findViewById estava apontando para "R.id.lances_leilao_maiores_lances" sendo que o correto deveria ser "R.id.lances_leilao_maior_lance", pode ser que na hora de preencher o android studio me deu várias opções e eu sem querer escolhi a errada que apontava para "R.id.lances_leilao_maiores_lances" última tag do layout activity_lances_leilao.xml.

Corrigi, problema resolvido.
