Bug 281744 ReflectionContributionFactory should log something when create(String, IEclipseContext) is unsuccessful
I made a mistake defining my MContributedPart's URI property but was not informed of this in the logs. This is because ReflectionContributionFactory's create(String, IEclipseContext) doesn't log anything if the bundle could not be retrieved.

Constructor<?> targetConstructor = null;
		Constructor<?>[] constructors = targetClass.getConstructors();

		} else {
			ArrayList<Constructor<?>> toSort = new ArrayList<Constructor<?>>();
			for (int i = 0; i < constructors.length; i++) {
				Constructor<?> constructor = constructors[i];
				
				if ((constructor.getModifiers() & Modifier.PUBLIC) != 0) {
					toSort.add(constructor);
				}
			}
			
			
			Collections.sort(toSort, new Comparator<Constructor<?>>() {
				public int compare(Constructor<?> c1, Constructor<?> c2) {
					int l1 = c1.getParameterTypes().length;
					int l2 = c2.getParameterTypes().length;
					return l1 - l2;
				}
			});

				for (int i = 0; i < params.length && satisfiable; i++) {
					Class<?> clazz = params[i];
					if (!context.containsKey(clazz.getName())) {
