I think we can do a more solid approach to that. Would be good to not to
rely on the context class loader.
1. You could use the classloader of the component type directly, i.e.,
`classArray = (Class<OUT>) Class.forName("[" + className, true,
componentClass.getClassLoader());`
2. You can directly obtain the array class via this trick:
`classArray = (Class<OUT>)
(java.lang.reflect.Array.newInstance(componentClass, 0).getClass());`
