Based on Michael's answer above, this code block worked for me to extend the default configuration — I had to wire up the Serializer to both the JobRepository.class and the JobExplorer.class:

@Configuration
@EnableBatchProcessing
MyBatchConfigurer extends DefaultBatchConfigurer {
    private final DataSource dataSource;

    @Autowired
    public BatchConfiguration(final DataSource dataSource) throws Exception {
        this.dataSource = dataSource;
    }

    @Bean
    ExecutionContextSerializer getSerializer() {
        return new XStreamExecutionContextStringSerializer();
    }


    @Override
    protected JobRepository createJobRepository() throws Exception {
        final JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
        factory.setDataSource(dataSource);
        factory.setSerializer(getSerializer());
        factory.setTransactionManager(getTransactionManager());
        factory.afterPropertiesSet();
        return factory.getObject();
    }

    @Override
    protected JobExplorer createJobExplorer() throws Exception {
        final JobExplorerFactoryBean jobExplorerFactoryBean = new JobExplorerFactoryBean();
        jobExplorerFactoryBean.setDataSource(dataSource);
        jobExplorerFactoryBean.setSerializer(getSerializer());
        jobExplorerFactoryBean.afterPropertiesSet();
        return jobExplorerFactoryBean.getObject();
    }
}
