Faulty classloading - unreachable code

                 Key: ABDERA-279
                 URL: https://issues.apache.org/jira/browse/ABDERA-279
             Project: Abdera
          Issue Type: Bug
    Affects Versions: 1.1.1
            Reporter: Antoine Toulme

The Discover class uses this method to get a class:

      private static <T> Class<T> getClass(ClassLoader loader, String spec) {
        Class<T> c = null;
        try {
            c = (Class<T>)loader.loadClass(spec);
            c = (Class<T>)(c != null ? c : getClass(Discover.class.getClassLoader(),
        } catch (ClassNotFoundException e) {
            throw new RuntimeException(e);
        return c;

However the first line inside the try statement will throw a CNF exception if the class cannot
be found. As a result, the second line is never executed.
c = (Class<T>)(c != null ? c : getClass(Discover.class.getClassLoader(), spec));

The code executes recursively, which makes things harder. I would recommend changing the way
the code is currently written to avoid recursion.
