SpringBoot integration tests failing with java.awt.HeadlessException

Updates after review and proposal from @Bobernac Alexandru

The question is updated with proposals, you can just use it directly ;)

I have an issue while running Springboot integration tests.

My test class

public class DepenseEndpointIT extends AbstractIT {

    private DonneesTestEndpointUtil donneeTest = new DonneesTestEndpointUtil();

    @Override
    @Before
    public void setUp() {
        System.setProperty("jwt", false)
        super.setUp();

    }

    @Test
    public void shouldReturnVentePrevHttpStatus200() throws Exception {
        String uri = "/agregats";
        MvcResult mvcResult = mvc.perform(MockMvcRequestBuilders.get(uri).params(params).accept(MediaType.APPLICATION_JSON_UTF8_VALUE)).andReturn();
        int status = mvcResult.getResponse().getStatus();
        String responseContent = mvcResult.getResponse().getContentAsString();
    }

}

AbstractIT looks like (I replaced for more readability package names)

@RunWith(SpringRunner.class)
@SpringBootTest(classes = DepenseEndpoint.class,
                properties = {"spring.cloud.config.enabled=false", "spring.cloud.zookeeper.enabled=false", "spring.cloud.zookeeper.discovery.enabled"})
@EntityScan({"si.data.analytics.ven.history.entity", "si.data.analytics.ven.history.domain"})
@WebAppConfiguration
@ComponentScan(basePackages = {"si.data.analytics.ven"})
public abstract class AbstractIT {

    protected MockMvc mvc;

    @Autowired
    WebApplicationContext webApplicationContext;

    protected void setUp() {
        mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }
}

When I run my tests, I have the following error, the exception is thrown, while doing mvn.perform(...)

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.util.concurrent.ExecutionException: java.awt.HeadlessException

In my main(), I have modified the way I run my application, I set headless to false to avoid the error, and it's working fine, but my integration test is not working:

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class})
@ComponentScan(basePackages = {"si.data.analytics.ven", "si.data.analytics.foundation.logging.aspect"})
@EnableAsync
@EnableDiscoveryClient
public class Main {
    public static void main(String[] args) {
        SpringApplicationBuilder builder = new SpringApplicationBuilder(Main.class);
        builder.headless(false).run(args);
    }
}

Is there something that I have missed ? Is there any way we can pass the same paramteter, i.e: builder.headless(false) to test classes ?

Thanks in advance for your help

I found a solution to overcome the issue, by setting java.awt.headless to false

@Override
@Before
public void setUp() {
    System.setProperty("java.awt.headless", "false");
    super.setUp();
}
