@Achim / @JB: Sorry for the misunderstanding. I didn't mean to ship a binary distribution with a JVM embedded, I meant to modify the scripts so that Karaf by default prefers a JVM if (and only if) one is present in a certain directory within KARAF_HOME.
In case none is there, just follow the same search order like at the moment (ie. first look for a JAVA_HOME env var and if that is missing search for a java binary in the path). That would be enough for users to package a JVM without needing to modify the setenv scripts...
