Several profiles in one yaml seems doesn't recognised correctly.

[alex-petrov81]

Spring-Boot version: spring-boot-2.0.1.RELEASE

Use case:
I have the following application.yaml

server:
        address: 192.168.1.100
---
spring:
        profiles: production | eu-central
server:
        address: 192.168.1.120
---
spring:
        profiles: development
server:
        address: 127.0.0.1

Also I have TestProfile class

@ActiveProfiles(value = "production")
@RunWith(SpringRunner.class)
@SpringBootTest
public class ProfileTest {
    @Autowired
    private Environment environment;

    @Value("${server.address}")
    private String serverAddress;

    @Test
    public void testProfile() {
        Assertions.assertThat(environment.getActiveProfiles()).isEqualTo(new String[] {"production"} );
        Assertions.assertThat(serverAddress).isEqualTo("192.168.1.120");
    }

}

And I've got an error
org.junit.ComparisonFailure: Expected :"192.168.1.120" Actual :"192.168.1.100"

The problem is SpringBoot always use default value for ${server.address} because framework couldn't recognise profiles: production | eu-central as a List of profiles. If I use
@ActiveProfiles(value = "production | eu-central")

then my test is ok.

I've found that problem comes from org.springframework.boot.context.config.ConfigFileApplicationListener.java

private List<Document> asDocuments(List<PropertySource<?>> loaded) {
			if (loaded == null) {
				return Collections.emptyList();
			}
			return loaded.stream().map((propertySource) -> {
				Binder binder = new Binder(
						ConfigurationPropertySources.from(propertySource),
						new PropertySourcesPlaceholdersResolver(this.environment));
				return new Document(propertySource,
						binder.bind("spring.profiles", Bindable.of(String[].class))
								.orElse(null),
						getProfiles(binder, ACTIVE_PROFILES_PROPERTY),
						getProfiles(binder, INCLUDE_PROFILES_PROPERTY));
			}).collect(Collectors.toList());
		}

the following line
binder.bind("spring.profiles", Bindable.of(String[].class)).orElse(null)
construct Document object and this object always contain profiles array with one element. In my case it contain Array with one String "production | eu-central". I think that is root of cause.

production | eu-central

This format is a Spring Framework 5.1 (and therefore a Spring Boot 2.1 feature).
