SpringBoot Spring Boot profile groups with recursive references end up in endless loop

While migrating conigurations to Spring Boot 2.4, I accidentally ended up with something like:

spring.profiles.group.myprofile: myprofile, other

The JVM failed to start with an out of memory error, I assume that this ends up in a recursive loop. I suggest that the recursive definition should yield and error or be ignored.
