The @ActiveProfiles throws exception while trying to overriding properties file values

[tamademicheli]

IS: while upgrading from SpringBoot 2.2.7 to 2.3.0, the overriding behaviour of @activeprofiles changed without notice on the migration. This test works with 2.2.7 and not with 2.3.0 https://github.com/tamademicheli/springboot230issueTestActiveProfile/blob/master/demo23/src/test/java/com/example/demo23/ActiveProfilesTestBackendTest.java

SHOULD: work in both version. if not please add to the migration path this breaking change and how we should accomplish to override properties likely as the linked test.

A similar issue which could be related to that:
#21302

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'mybackendvalue' in value "${mybackendvalue}" at org.springframework.util.PropertyPlaceholderHelper.parseStringValue(PropertyPlaceholderHelper.java:178)

This change was caused by a bug fix (#19537) that prevented profile names containing commas from being activated. To enable multiple profiles, you should provide each as a separate value, as in

@ActiveProfiles({"backend", "test"})

Added to the 2.3.0 release notes: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#activating-multiple-profiles-with-activeprofiles
