Type enforcement: · Options are automatically constrained to the Java type in the interface.

Enum support: · Options defined as an enum type are automatically converted. · Regular Expression argument validation · A regular expression can be specifed for each option, which the option's values must match. Requirements: · Java What's New in This Release: · fixed bug with enum lists
