How to store keystores in profile and accessing it in Spring context ?

Issue

• We noticed that the mq-default profile has io.fabric8.mq.fabric.server-broker.properties file with property keystore.url=profile\:keystore.jks.
• We would like to also place our keystores in our profiles and be able to access them from our Spring config.
• We have defined the property in a property file in the profile like this:

keystore=profile\:keystore.jks

• And this is propagated to the Spring context and used with the following:

<sec:keyManagers keyPassword="changeit">
    <sec:keyStore type="JKS" password="changeit" file="${keystore}"/>
</sec:keyManagers>

• But we get

java.io.FileNotFoundException: profile:keystore.jks
