 113         public Option(boolean hasArg, Processing<T> processing, String name, String shortcut) {
 114             this(hasArg, processing, false, name, "");
 115         }

should be this(hasArg, processing, false, name, shortcut);

 152             } else if (trimmedName.startsWith("-")) {
 153                 trimmedName = trimmedName.substring(1);
 154             }

Per JEP 293, jlink is a new tool that should have long form option names.  This can be simplified (these 2 lines not needed) and the resource bundle key uses the long form name.  Option constructor should validate the name parameter with two slashes prefix.

Otherwise, looks good.
