DATACMNS-1206 - Polishing.

Convert type array to string to construct the exception message. Slight Javadoc tweaks. Reduce method visibility. Simplify hasDefaultGetter check. Remove superfluous throws declaration. Strip trailing whitespaces. Ignore property descriptors without getter (e.g. indexed properties).

Original pull request: #263.
