1781         sb.append("\n[").append(ename).append("]”);
1786         sb.append("\n  name ").append(md.toNameAndVersion());

We can make jar -d output similiar to `java —-list-modules` and have the entry name next to the module name in the same line.  

module hi (module-info.class)
module hi (META-INF/versions/10/module-info.class)

1759-1763:  an alternative is to use stream().sorted().foreach(…) that you won’t need to create the names array.

Otherwise, looks okay.
