Generating resource yamls logs error because keys are not of type String

[a3aanwisse]

Description

When running a mvn fabric8:build on our project the logging shows the following error:

F8: f8-healthcheck-spring-boot: Error while reading the spring-boot configuration: java.lang.IllegalArgumentException: Spring Boot configuration file my-module/target/classes/application.yml is not formatted correctly. Expected to find a key of type String but class java.lang.Integer with content 123 found.

The reason for this failure is the fact that our application.yml contains the following structure:

my:
  map:
    123: some-value
    456: another-value

The https://github.com/fabric8io/fabric8-maven-plugin/blob/master/core/src/main/java/io/fabric8/maven/core/util/YamlUtil.java reads the keys of the my.map as Integers instead of Strings.

So the code on line 69 throws an IllegalArgumentException, however Spring is OK if I use a map with a key of type Integer.

Suggestion: make code robust for other types OR change the Error in a Warning.
