Property replacement does not work for management.server.port since spring-boot 2.1 #15354
Description
Consider the following patch against spring-boot-sample-webservices:
diff --git a/spring-boot-samples/spring-boot-sample-webservices/src/main/resources/application.properties b/spring-boot-samples/spring-boot-sample-webservices/src/main/resources/application.properties
index 2453faa0be..c6a1571aed 100644

+m1=12345
+management.server.port=${m1:0}
spring.webservices.wsdl-locations=classpath:META-INF/schemas/
The maven build now breaks with
[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.121 s <<< FAILURE! - in sample.webservices.SampleWsApplicationTests
[ERROR] testSendingHolidayRequest(sample.webservices.SampleWsApplicationTests) Time elapsed: 0.001 s <<< ERROR!
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.lang.Integer] for value '${m1:0}'; nested exception is java.lang.NumberFormatException: For input string: "${m1:0}"
Caused by: java.lang.NumberFormatException: For input string: "${m1:0}"
This is the case at least since 2.1.0 and still does not work in 2.1.1.
Interestingly, this does only happen in the test.
The deployment start properly with java -jar spring-boot-sample-webservices-2.2.0.BUILD-SNAPSHOT.jar
