Karaf 4.0.x build is broken

[Jean-Baptiste Onofré]

Hi guys,

As you can see on Jenkins, the karaf-4.0.x branch doesn't build due to 
this commit:

https://github.com/apache/karaf/commit/cfda72ece434f6c75af95f7327f5ad1f790c4038

As reminder, Karaf 4.0.x supports both Java7 and Java8. So, the Java 
target source level is Java7.

So, something like:

    public URI[] getRepositories() throws IOException {
        load();
        return features.getRepository().stream()
                .map(String::trim)
                .map(URI::create)
                .toArray(URI[]::new);
    }

is not allowed on Karaf 4.0.x (it is on Karaf 4.1.x/master as the Java 
version is 8 and 9).

I'm fixing that.

Regards
JB
