This small project demonstrates an issue with spring boot 1.5.2 and spring-config, when spring-cloud-starter-config is added to the classpath.
The test com.example.DemoApplicationTests only works when spring-cloud-starter-config is removed from the pom.xml.
There is an additional strange thing to discover in this setup: if I revove the annotations @NotEmpty and @NotNull in com.example.config.MiscConfigInfo then the app starts properly, but one can see that the same bean is created twice and ad the end the Map<Integer, Boolean> kmsToWarning will hold some very strange values.
There is a simple log entry when an instance of MiscConfigInfo is finished with initializtion, I would expect:
listener -->true
kmsToWarning -->{50=false, 10=true, 30=false}
to be in the logs once, but instead I see it twice and even with duplciated entries in the map(????):
listener -->true
kmsToWarning -->{50=false, 10=true, 50=false, 30=false, 30=false, 10=true}
Here is the full log:
