Simone Tripodi commented on DISCOVERY-17:
-----------------------------------------
you're right Joerg, after reading the doc I'm convinced that the commit related
to this issue has to be rolled back.
thanks for reviewing!

> I find the current Enumeration behavior broken, but please tell me if I'm
> wrong!!!
> This is the actual current behavior:
> {code}
> return new Enumeration<S>() {
> private S object = getNextClassInstance();
> public boolean hasMoreElements() {
> return object != null;
> }
> public S nextElement() {
> if (object == null) {
> throw new NoSuchElementException();
> }
> S obj = object;
> object = getNextClassInstance();
> return obj;
> }
> private S getNextClassInstance() {
> while (services.hasNext()) {
> ResourceClass<S> info = services.nextResourceClass();
> try {
> return spi.newInstance(info.loadClass());
> } catch (Exception e) {
> // ignore
> } catch (UnsatisfiedLinkError ule) {
> // ignore
> } catch (ExceptionInInitializerError eiie) {
> // ignore
> }
> }
> return null;
> }
> };
> {code}
> but it should be
> {code}
> return new Enumeration<S>() {
> public boolean hasMoreElements() {
> return services.hasNext();
> }
> public S nextElement() {
> ResourceClass<S> info = services.nextResourceClass();
> try {
> return spi.newInstance(info.loadClass());
> } catch (Exception e) {
> // ignore
> } catch (UnsatisfiedLinkError ule) {
> // ignore
> } catch (ExceptionInInitializerError eiie) {
> // ignore
> }
> return null;
> }
> };
> {code}
> I think there's no need to comment both codes, please tell me why the first
> one should be right :P
