Accessing java files from Eclipse source-bundle

How do I access source code from an Eclipse/OSGI source-bundle?

I use Maven/Tycho to produce the source bundles using the source-feature packaging. This works well for attaching the source for 3rd party development. They are referenced on the JAR as 'External location' for 'Java Source Attachement'.

But how do I programmatically reach the source-bundle? Source bundles are not accessible as regular bundles, ie Platform.getBundle('com.myplugin.source'), and the source files are not accessible through the master bundle, ie 'com.myplugin' There's no reference in the plugin manifest headers either. Is there an Eclipse OSGI service that I should use? Any help would be appreciated.

Not the solution I was hoping for but as a workaround I can go directly to the source bundle JAR file. I would hope there is a better solution as I am not sure this is future proof with such as Oomph.

String bloc = Platform.getBundle(bundlename).getLocation();
String location = bloc.replace(bundlename, bundlename+".source");
String path = new URL(location.replace("reference:", "")).getPath();

// Depending on installation type it may to prefix with Eclipse's installation path
if(!new File(path).exists())
    path=Platform.getInstallLocation().getURL().getFile()+path;

File srcbundle = new File(path);
if(!srcbundle.exists()){
    Logger.IDE.severe("Source bundle '"+path+"' not found!");
    // When in runtime workbench we will get the source files from the bundle
    for (URL url : Collections.list(bundle.findEntries("/", "*.*", true))) {
        try(InputStream input = url.openStream()){
            outputFile(input, url.getFile());
        }
    }
} else {
    // When plugin installation we will unzip the source bundle JAR. 
    try(JarFile jar=new JarFile(srcbundle)){
        for (JarEntry ze : Collections.list(jar.entries())) {
            try(InputStream input = jar.getInputStream(ze)){
                outputFile(input, ze.getName());
            }
        }
    }
}
