Missing String.format parameters in DefaultJavaObjectFactory

[paulkrause88]

Any exception caught by cacheNewInstance is lost due to the missing args.

The code was probably intended to be

 private <T> T cacheNewInstance(Class<T> type) {
        try {
            Constructor<T> constructor = type.getConstructor();
            T instance = constructor.newInstance();
            instances.put(type, instance);
            return instance;
        } catch (NoSuchMethodException e) {
            throw new CucumberException(String.format("%s doesn't have an empty constructor. If you need DI, put cucumber-picocontainer on the classpath", type), e);
        } catch (Exception e) {
            throw new CucumberException(String.format("Failed to instantiate %s", type), e);
        }
    }

Paul, fork the repo, add a failing test and change the cacheNewInstance method as you suggested above.
